Deep ToT is not what i meant, i should have been more clear about it, apologies!
What i meant was at least in-house production of missiles so we can make them in numbers. The point being that it will not only meet our immediate needs in Medium level air defense shield (the long range will surely be bought in very limited numbers and will be an of the shelf product) but will also help us study the mechanism, missile thruster motors, radar seekers and guidance system.
I fully agree that we should think 20-25 years ahead when it comes to military systems since we are not one who will be changing there equipment every few years. That means we should be working on our anti-air missiles (both surface and air launched ones) and for that there are a number of components that we will have to study.
If there are options available, like the ones you mentioned, that can be joined and procured in near future and have added benefit for naval platform (in its ability to be quad packed) then yes, Pakistan should surely join such projects. Standardization across all forces will be a huge asset as well. If there is some program like the one you mentioned that can be meet the needs of army and navy or navy army and air force then yes, we need to join that at the earliest. Even an SD-10 with better range (150-180Km) land based version along with one that can be quad packed for naval platforms will be EXCLLENT. Perhaps we should look into that as well since SD10 is going to be our primary BVRAAM for air force.
On a lighter note sir, frankly speaking, by the way our current SAM capabilities are i will really take anything and everything that can be acquired. We do need to at least get in place a medium level ground base air defense system. Although it will need money but need to keep moving in that direction. Even with advancements in war planes and there EW capabilities, SAM are here to stay for quite some time (specially considering there anti missile role and anti-UAV role).
BTW, do you think that some work can be done even on this system to get it to a dimension where you can fit four in one VLS cell?

Perhaps remove the tail fins and make it a bit slim? I guess it is a bit too fat at 34cm dia.
I am sure the seekers are not a problem, it is the main rocket that we need to get right (any option we choose) and eventually we will get it with a variety of different seekers.
EDIT:
The more i read about UMKHONTO the better it looks.
Just need to work on range a bit more. 80-100 Km is what we should be looking at.
Do you think there are any chances we can join this program and go for this system?
