I was thinking of using the toy box mod to almost completely change every companion I come across. I'd keep the name, voices and genders, those don't matter to me not. However, are there any companions that I should NOT change specifics on so as not to break any quests or anything?

Like, if I wanna change race, looks, alignment, class, diety, etc... Should I avoid it on specific characters? Like with how Seelah always talks about Iomedae, should I avoid changing that? Or with Camille and her alignment, would it hurt to change that?

I've only gotten to literally just finding Ember before I last got off the game, so no spoilers necessarily please, but if you were to list the names of the companions and what not to change, I would really appreciate it. I'm willing to test it out as well, but for those who already have the info, it would help me not to get halfway or more through the game and find out I have to start over because something broke. Thanks in advance!

For those that may mention the mercenaries you can fully customize, I know about them, but I'd really like the dialogues and quest lines of the pre-made characters. Just wanna make them more customized to my liking.
