Is threre a way to change a character's model to appear like a lizardfolk or gnoll? It would still use the old char's stats, but would now look like a lizardfolk.
As far as I know (and it's not a great deal) the game contains text lists of what body parts make each creature, NPC or PC. From this I think you could tell it that a male halfling, for example, has a lizardmans body and tail and head etc.... I don't know, however, if there are specific animations for weapons and so on that would cause problems. For example it might cause a crash if you stick a longsword on the PC and the game tries to find the animation for a longsword and can't. Or if the game tries to find the animation for the lizardman casting a spell, and can't. My advice is to extract the files (I think it's in the 3rd .dat) and read through them and carefully tinker and see what happens.
