The logic is basically to make it the ultimate heavy tank by taking an awesome vehicle and getting rid of its one weak point (few shells + slow reload + cramped insides) by giving it a less awesome but still big and nasty gun so as to not have to modify the outline of the bits people are inside of in any meaningful way. Basically think IS-2-85 or something.
IS-2 is cramped full stop. Switching the gun out won't change that. Same with ammo capacity. 28 isn't really a small amount, but you won't be getting much more with late war single piece AT rounds.
In fact because you will get like, a hand full in the bustle next to the TC, the rest will have to be in boxes under the turret. I'd be surprised if you could get any meaningful amount more than IS-2's 28 rounds. IS-2 has the advantage of having smaller individual components for the shells for its smaller internal space. Loading a Kwk 43 or M3 or anything that big inside there would suck major ass.
