Sorry, I thought I had replied earlier to say thanks for the suggestions. I gave Full Custom Companions a go last night and created a clone of the lead character from my other game. But the companions are a bit harder, because the companions I want left the game long ago (different companions in each game), so to get them back I'd have to go back to act 1. I'd like to have Minthara in the evil party, but also not to have to play through hours of game just to set up one picture.
The best solution I can think to try is using LsLib to edit a database to find flags for which companions are in/have left the party and put them back in; and probably go it in the save from the good party, because in that game I've got white-haired Shadowheart and horned Wyll, whereas in the evil game I've just got the half-illithid appearences, which I can probably do on the spot by feeding them tadpoles.
But if anyone has a better suggestion, I'm all ears. Otherwise I might just have to set up an argument between Tav & Durge instead of the battle scene
