I know this isn't about BG2 but there isn't a P:T board on the Ironworks forum.
I really enjoyed playing Planescape:Torment but now I've completed it it's a bit limited in replayability due to the limited number of NPCs, who can't be customised much either in terms of equipment. I'd really like to play a party with some more of the weird and wonderful creatures and factions in the Planescape universe!
I have found a couple of savegame editors that let you change stats, class etc for P:T but not the appearance (avatar/sprite) or portrait. Are there any others that can? Perhaps the creator of Gate/Dale/Shadowkeeper could create a "Planekeeper" in the future.

I think there already is one, not sure though.

There isn't an editor in the Gatekeeper series for P:T, though there's one for all the other Infinity Engine games.
There are a number of other P:T saved game editors but they don't allow you to change the appearance, name, etc. of a character.
