what are you talking about anyway? it's just the KSS framework friends it can with anything, even with VP.
Why you framework for the topic? What would the developer after you sat down and looked at another code? Why not take the starting topic type _s

Try to follow the WordPress Codex
, then there will be no problems do you have with the design nor the one who will develop
