Rather than tweaking the game and having to worry about balance issues cropping up, it'd be sweet if they included a quasi-GM mode where the only thing you could tweak would be ability scores, saves, VP, FP, and attack bonus. Leave it up to the user, make it an optional mode for those looking for a different experience on the replay. Just off the top of my head, you could prevent incompatibilities arising (like the user lowering an enemy's stats and rendering him ineligible for his own feats/equipment) by only allowing users to raise stats. Actual devs could probably come up with something a lot more elegant.
Not that this is something i actually expect to happen in this universe. It does seem like something that'd be fairly easy to implement; you could go for a bare-bones GUI, or maybe (possibly? i'm no programmer) have a folder of text files the game uses to call up character's stats. Wouldn't even need an interface in that case.
