VRC: Customizable Avatars

Coming from SL to VRC, I was surprised at how little end-user customization is available with regards to avatars. Avatar makers do some amazing work here, but in the end you are limited to:

1. Diving into development tools yourself
2. Hoping your favorite avatar maker provides enough handles that you can adjust things to "close enough."
3. Hiring someone to make you a custom.

All of these are good options, but what if could build something more like selecting an outfit? Ready-Player-Me does this, can we build an open-source version? Early work, let's start with a custom t-shirt maker for a specific avatar and go from there.
