Only for things I claim, not for thing I didn't claim.
Besides, I'm doing this for recreation, don't HAVE to do anything and you cannot make me do anything.
However, as indicated, if Raytheon comes up with a concept involving a large (probably steel) structure atop the bridge with 3 radar arrays, while retaining 3 AN/SPG-62s in their original places (a concept which I assume they wouldn't put forward if it wasn't technically feasible), I don't see why a different modification involving a sleek and light structure (e.g. alu) with a four faced APAR isn't possible e.g behind the second stack.
The above deck weight of Thales APAR is lt. 11 tons.

A single AN/SPG-62 antennea weighs 1.225 tons, so three weigh 3.675 ton that can be deleted

Discart the AN/SPS-67 (0.3 ton)

AND DO NOT replace with AN/SPQ-9B (0.68 ton)
http://www.navy.mil/navydata/fact_display.asp?cid=2100&tid=311&ct=2
Weight thus saved: 3.975 ton
There are three antenna arrays on the Raytheon concept. What do you think: they weigh more or less than 7.025 tons i.e. 2.342 tons each? Consider that the 4 smaller arrays of APAR in a typical square structure are <11 tons (i.e. < 2.75 ton per side, of which 2 tons is array only), that is.
Additional weight could be saved by (wholly or partially) cutting down the structures beneath the front AN/SPG-62 and the rear most AN/SPG-62 (which hold equipment associated with these illuminators). And of course: by not having that large (easily 2 deck levels!) addition (and whatever it contains) atop the bridge in the first place!
APAR could be located directly behind the rear stack (highest point, least additional mast structure).
Consider also that e.g proposed 4.5k ton PF 4921 frigate based on USCG National Security Cutter employs both CeaFar (6 elements) and CeaMount (4 elements) on a mast similar to that of Burke. Something using CeaMOUNT only could be even smaller.

Says you.
As you pointed out about Arleigh Burke, Flight 1 is not Flight 2 is not Flight 2a etc. So, why then do you assume the ANZAC (MEKO 200ANZ) as originally delivered, is the same as the ANZAC when it got the new mast with CeaFar and CeaMount?
The armament initially consisted of a single 5-inch gun and a point-defence missile system (an eight-cell Lockheed Martin Mark 41 Mod 5 vertical launch system for RIM-7 Sea Sparrow missiles as a point-defence system), supported by a missile-armed helicopter. Sure, it had a lot of margin then!
The ships were delivered "fitted for but not with" a torpedo system, two quad-canister Harpoon anti-ship missile launchers, a second Mark 41 launcher, and a close-in weapons system. All ships were "fitted for but not with" a towed-array sonar, with the RAN and RNZN following separate acquisition programs for these. The frigates were also "fitted for but not with" SATCOM and a Helo datalink.
However, you ignore that since entering service Mark 32 3-tube torpedo launchers taken from other, retiring ships were installed. Phalanx CIWS weapons system, recycled from decommissioning various
Leander frigates, were fitted to each new frigate in New Zealand service. In 2003 ESSM began to replace Sea Sparrow (i.e. 32 missiles instead of 8) in RAN. Harpoon was installed across the RAN vessels from 2005 onwards. The original planned location on 02 deck was found to be unsuitable, and the launchers were relocated to 01 deck, in front of the bridge. Around the same time, the RAN began to fit these frigates with two M2HB .50 calibre machine guns in Mini Typhoon mounts, installed on the aft corners of the hangar roof, with two TopLite EO directors. A Petrel Mine and Obstacle Avoidance Sonar system was added. Also installed were a Vampir NG Infrared Search and Track system, and Sharpeye Navigational Radar Systems. All this before Perth became the first to undergo the ASMD project in 2010.
On 18 January 2010,
Perth docked at the Australian Marine Complex in Henderson, Western Australia to be modified under the Anti-Ship Missile Defence Project, which included the fitting of CEA Technologies' CEAFAR and CEAMOUNT phased array radars.
Both of the frigate's masts were replaced. The new aft mast is taller and sits at 38.7 metres. The new foremast is lower. Additional ballast was added to improve the frigate's stability, and the ship's quarterdeck was enclosed

Nah, not really. See above.
LOL. I know better than most here what GAO is and does. Point is, they aren't naval enginees and architects, and their reports aren't automatically final or even necessarily consensus based (often include responses why various other agencies do not have the same view). Besides, this is a forum, not a US government agency. I take it one is free to explore in a forum setting. You claim I make up information, but that is all that you do: claim. As you pointed out, if you claim, on you is the burden of proof.
Anyway, less different than NUNS and GANG BANGERS! In reality, however, any and every ship has a limited margin for growth....
See above. You are getting all upset over ... nothing.
Folks here asked if we could stop bickering about ABIII. I already indicated my willingness to do so. Therefor this is the last post I am putting here on this topic.
I suggest you take a good sized chill-pill.
