There's actually something interesting about this. I believe the game looks for the individual player IDs from the original classic team rosters when loading the Jordan Challenges, and not the player themselves. If my theory proves correct, you can overwrite the players with Reditor without changing their individual IDs (this is how you can get the rest of the real players in there, and the appropriate starting five for certain teams). I believe I was able to overwrite Cliff Robinson with Kevin Duckworth a while back and it worked. There's also an instance where the '86 Bulls' rotation setting would adamantly put Geroge Gervin as the starting SF over Woolridge, which would prompt the default rosters when loading The Arrival.
For 2K12, you can use custom rosters for NBA's Greatest with the Legends Showcase DLC. The DLC allowed for roster editing for the classic teams (you couldn't edit them at launch), and you could assign anybody to those teams and do resimulations of the games.
