I really hope this project is still ongoing in the background and hasn't been abandoned.
Another project that needs a set like this to exist is the Commodore 64X which recently had a successful Kickstarter.

The project is developed by My Retro Computers LTD which has been using C64 molds for awhile.

Novelties for the 5 large buttons on the side would be fantastic.
But all that being said, I really want to see this set come out in any shape or form. I even really liked the original colorway on it!
Edit: There's also the Command 65 keyboard to consider!
