But shouldn't we be careful while only making estimates based on the above deck space? I mean any VLU will take up below deck space too, associated wiring perhaps etc.?
The Barak 1 VLU takes up space below deck, it you have a longer VLU needed for SRSAM and you go higher, there is no need for more depth below deck than with Barak 1. Barak 1 is 2,2 m long. VL Mica is about 3m long and fits the Sylver A35 VLU. At most you need half a deck extra height, that's why I was looking at the ELTA STIR location. Go figure.

Honestly though, unless the below deck space between the foremost Barak VLUs and the AShM VLU has been taken up by something or cannot be sacrificed for some reason (could it be that the AShM VLU needs the extra empty space for servicing or on-shore reloading procedure? Dunno), it should be easy enough to fit another 16 Barak cells.
You might consider it is a command vessel, perhaps it has additional needs for spaces for command purposes.
I am more concerned about the point defence, CIWS system and VSR.
I believe that was what we were discussing: Barak 1 and AK630?
How would you compare the AK-630 with the Oerlikon Millennium CIWS? I believe that the Oerlikon guns do not require any below deck penetration and do not require a supply of coolant or the ship's power to operate?
Millennium is far superior to AK630, not in the last place due to it firing a far bigger round (35 x 228 mm, at 1000 rpm versus 30 x 165 at 6000 rpm).
Round length (complete round) AK630: 29.3 cm
AHEAD: 15.23 in (38.7 cm)
HEI: 15.23 in (38.7 cm)
APDS-T: 13.39 in (34.0 cm)
Round weight AK630: 0.832 - 0.834 kg
AHEAD: 3.90 lbs. (1.77 kg)
HEI: 3.48 lbs. (1.58 kg)
APDS-T: 3.19 lbs. (1.445 kg)
Warhead weght: AK630: 0.0117 kg - 0.0485 kg
AHEAD: N/A (uses 152 sub-projectiles of 3.3 gms each)
HEI: 0.25 lbs. (0.112 kg)
APDS-T: N/A - solid penetrator weighs 0.666 lbs. (0.302 kg)
Muzzle velocity AK630: 860-960 m/s
AHEAD: 1,050 m/s (3,445 ft/s)
HEI: 1,175 m/s (3,854 ft/s)
APDS/T: 1,440 m/s (4,724 ft/s)
max. effective range 3500m (3830 yd) AK630: 4000m
But, the gunmount weight 3,3 tons versus 1850-2500kg.
Also, apparently the Maitri SR-SAM does require a sensor analogous to the STGR for the Barak-1s, its called the Revathi, so I guess any retrofitting of the SR-SAM will still require removing the foremost CIWS guns, under such a circumstance I'd like to see the AK-630s get moved out completely and replaced. I'd personally be happy with 32 LR-SAMs and 32 quick reaction SR-SAMs along with a 3D VSR like the RAN or SMART-L, the last two additions would be MORE THAN ENOUGH IMO.
How so, if it is to be Infrared and/or Active radar homing like Mica is? Barak 1 needs a radar director because it is CLOS (command to line of sight = not homing).

You can't have a ship with just a 76mm cannon, you need something smaller e.g. to take out small boats.
