Character Customizer (Version 4)

Hi, this system looks perfect for my project, but I have a few questions:
1- is it possilbe to create old looking people with this system also? (maybe just by replacing the textures?)
2- can different beards and mustaches be added, the same way as adding custom hair?
3- would it be possible for you, if you find the time, to make some screenshots or a short video of some examples of different options of the face morphs? like how different the noses can look etc.
Thanks for creating this!
