#EvilThought : fork #Mastodon and stick the Pleroma frontend on top of it.

Bonus points if you make it only use the #Tent protocol.

I haven't looked at the source, but ideally the mastodon frontend and backend would be loosely coupled, making it not even necessary to fork it.
Mastodon has a client API, so you should be able to use a web server as a client. Whether that scales is a different question :)
