An amazing roster creator Ruud2You has also started this project since early this year for PS3, but hasn't released a first version yet. So PS3 guys are very lucky to have this to look forward to. You should reach out to him and maybe combine your efforts with his somehow. (But I did find posts mentioning he likes to edit alone to account for any potential problems during the project.)
Here are Ruud2You past posts:

He used to make rosters for xbox360 keeping that game alive for a couple years (15& 16 seasons) but his game may have crashed or game gave an error about reaching limit to update data so he could not edit all of the teams. So he has moved on to PS3. Lucky for PS3 guys. And
Cardinal is making spreadsheets of every player from ncaa10 to help with roster player data source info on all college basketball rosters. So that's helpful for roster makers of this game.
"This game is definitely alive for PS3!"

There may also be one more person making ps3 rosters:

Fortunately for all of us, there are still dedicated roster creators working on this!

Update:
Xbox360 rosters stalled past couple years due to
an error of reaching a maximum limit to add more edited players to the base roster used from 2014 ..I found posts mentioning it here: (not sure if PS3 will ever have this problem years from now, but all is good today so far).

But fortunately Xbox360 has a new roster creator(bucks2bucks) who is trying to get this thing going again.
