I'm looking forward to this, originally Dee4Three had planned to get this going, but with him taking absence I'm glad to see others stepping in. We need as many people to help out, especially with cyberfaces.
mickachiste has suggested to help, he has made the retro rosters in the past like 84-85 Roster. I think we should really be pushing for accuracy here, no half arsed jobs like in the past. Take a look at previous renditions of 96-97 rosters, a lot of inaccuracies and mistakes. Things like the 50th Year anniversary logo on courts give the roster a uniqueness, even though they used it for half a season I think it looks cool:

Apparently people really don't like nicknames, so I hope AlvaroXXV isn't making players through create a player. It's not a huge problem for me personally but I suppose hearing nicknames being used by commentators could become annoying. Also stadiums is a big problem because of modern stanchions/dornas/led displays not being accurate to the current time. Perhaps maumau could help with that?
I'm planning on making every single jersey, home/away/alternate/throwback etc. I hope it doesn't go to waste
