Yes, please, even just small additions would suffice, for a while anyway.

About faces... I'd honestly prefer them not to add more, and instead get rid of that completely by having one face and then putting all of the different eyes, lips, nose, facial markings in the "facial features" tab that has them toggle on/off options (like the scars, forehead spots, etc); for example, if I wanted to be a red nose sporting, face 2 marking, face 1 lipped Seeker Miqo'te then I would just simply check them boxes and voila - new face!

Personally, I think that would be a nice first step in introducing more options without creating actual new looking face stuff etc. Then later there could be incremental additional eye, nose etc options added.
