What about this: Let players load their own pictures.
Maybe there is an easy way to add your own pictures to the profile-pool in the game data, even if there isn't an upload button. Maybe some people will make an online Profile-Pic editor or something.

What would also be nice is if they would add all the profile pictures they already (from npcs for example) to the pool, and if they would add a few pictures without a face at all (just colored background, or an emblem - they could use what they already have, class/skill emblems for example, or skill icons)
