This really can pertain to any of the gold box games, as I believe they use the same engine, as it were, with little change.
Is it possible to modify your party's action / character/ what have you/ Icons? I notice when you play the demo it uses character models you don't seem to have access to. It'd be nice to have access to some of those models, or even some of the enemy npc's, perhaps with a color change.
I do believe I've run myself ragged scouring the net for some information one way or the other, and frankly I'm rather surprised that there isn't even one mention of someone modding that option in somehow.
