1. I don't know about twig but I simply copy and modify default theme to create my own.
2. Have you check on the addon board / page for that?
3. I have created few addons on bbc. It's not so tough.

Swapping out the current template system for Twig would be a huge undertaking. The current system uses native PHP. It's not hard to understand, but it is less "nice" than Twig.
I know there is a plugin for SMF to do sub accounts. Not sure about Elkarte. Since Elkarte is a fork of SMF, it might not be hard to port it over.
Custom BBC is pretty easy. There should be a topic around on how to do that.
