I think as an option, perhaps also for online, they could try to remove those parameters altogether and let you fight with your own physical prowess (or lack of it) unfiltered, or add handicaps at best. Whatever they do, I think they should reskin this technology a few times over if they can for different audiences.
How about having that as mode for SP also? Call it "Keeping it REAL" or something, then the progress tracked will be yours and not some extra stat.
I got the game, but had no time to play with it yet.
