Tweaking WWII Tank Designs To Carry A Bigger Gun?

[dy031101]

Going beyond merely refitting WWII tanks with the biggest modern guns that can be carried and inspired by Yugoslavian Type 636 tanks, whose relationship with the T-34 seems rather apparent, what would other WWII tank designs altered to take a bigger turreted gun look like?

Setting the main armament to US-made 90mm or Soviet-made 100mm- say, you need to deal with primarily T-34s or 76mm-gun-armed Shermans, perhaps even a few T-54s or M26/46/47/48s- set up a turret around that gun and then have the chassis and hull suitably enlarged to take the turret.

Also assuming that, if necessary and available, old engines with better ones to cope with higher weight (IIRC, open-topped turrets fell out of favour post-WWII, not to mention the possibility of being up-armoured with better-strengthened and/or even applique plating) although such changes are not always visible for the purpose of general modeling topics.

Of course this concept is nothing new on this forum.  wolfik did one based on the Sherman.

Others have more-readily-made development as a basis.  Like the ARL-44 from Char B1 and Char G1, IS-3 and T-10 from IS-2, AMX-50 from Panther and King Tiger, and the afore-mentioned Type 636, seemingly based on the T-34 (a picture is available here).

The T25 (if you are stuck with HVSS suspension but could improve most of everything else about the Sherman):



Stretched Cromwell/Comet (of which the properly-widened, according to rickshaw, Avenger is better, but I couldn't find a drawing for rough draft):





Or the Black Prince, whose hull I took for use in this rough draft to represent an enlarged Churchill development:
