Is it possible to fit both byler and Mike/El break up in the finale?

I still believe in Byler for finale but there is one thing I’m concerned about that I’m curious how other post vol 2 Byler believers feel about.

After the second volume I don believe in the theory that El and Mike are already broken up anymore and that means that in order for Byler to happen this needs to be addressed too. And to do that in one episode feels very rushed, almost impossible.

What are your takes on this?
