My primary reason for preferring to play a non-Origin PC, is that I'd rather discover who my character is in the course of playing rather than try to determine who they are at the outset. That said, one thing I really liked in DOS3 was that at various points in the game (the beachcomber in Fort Joy, the elf in Fort Joy who asked if my character's tribe had similarly few children, Ifan when trying to determine your Lone Wolf name) asked you some rather revealing questions about yourself. I would be happy for them to do a little more with similar exchanges, e.g. using them to assign additional tags.
My concern with additional content for custom characters is the same as my concern about voiced protagonists. It can be great if the content/voice fit your character, but an irritant if they don't. However, so long as it doesn't feel inappropriate for specific characters and doesn't threaten to take too many resources away from other areas of the game, I'm fine with it, even though I'm also fine if it doesn't materialize.
