How feasible would be write a plugin to transform a shared stage into a session-scoped fixture?

I just came up from the doc in usefixture session, and I really enjoyed the way it was designed. I just would like to have the same capabilities to transform/wrap a shared stage into a session-scoped fixture like that, because I would like to avoid writing http requests in Python code, since we're already using Tavern.

Would any of you have an idea on how to achieve that? Some guidance on what to look for? Great tool by the way, I'm learning a lot and enjoying it so much. Thanks for all your efford maintaining it.

This can't be done because stage execution is done after fixtures are actually evaluated, and all the code to check responses and format variables etc. in stages is fairly intricately tied in with the inner workings of all the code that runs the stages the way it is now.
