I've always wanted to mod 96 as it is one of my favourites of the era, but like 95 it is very tightly packed in terms of flexibility for additional teams. I honestly believe you'd have to extend it to 4MB in order to get it to work, and even at that, a lot of the mathematical functions for calculating stats and building season data would have to be altered and expanded to accommodate 32 teams.
It's a big job. Not saying it can't be done, but it would take a lot of free time and dedication. (I have neither atm, so don't ask LOL)
