I would like to suggest making all BG1, BGII, and ID portraits and voice sets available across all three games. When I went to play BG1:EE for the first time, I wanted to play a half-orc, but then realized I was limited to using Dorn's portrait if I wanted to have an actual portrait of a half orc (and I didn't want to do that because I wanted to use him as well, without him having a mismatched portrait). I then realized that none of the available voice sets really sounded like a half orc either, so I switched my character up. Being able to use portraits or voice sets from all three games would make character building much more interesting. The portraits at least don't seem too difficult to do; even I could do that work just by screenshotting and resizing them.
I know that you can probably find a download somewhere on the internet to put the portraits into the game (not sure about the voice sets), but I think it would just be nice if they already came with the game. Variety is good, and I think having all of the materials from all three games easily accessible would make customization better. I understand it was initially posted that Icewind Dale content couldn't be used because of legal reasons, but since that post was made it seems Beamdog now has the rights to Icewind Dale, so I figured I'd go ahead and make the suggestion anyway. At the very least, a few new portraits for half orcs would be nice (there isn't even one of a female half orc in BG).
