Would the M26/M46 hull be able to take the Ikv-91 turret refitted with 105mm gun?

Actually your previous tank profiles make me think......
Say, we've got a whole inventory of Interwar-era and early-WWII tanks that we need to press into service in support of an insufficient number of modern tanks (as in Sherman, T-34-85, or Panzer IV). What would be your choice of armament for those upgrade older tanks?
I'm under the influence of my recent "Tank Hunter" WoT inventory theme to think of smaller-calibre, high-velocity guns. ZiS-4 used by T-34-57 seems to be the best performer, but would there be other guns that have a better balance between, size, adequate anti-armour capability, and handling (as many of those old tanks feature two-man or even one-man turrets)?
