Jetbrains appears to be making some effort to "modularize" the IntelliJ platform. I'm not sure exactly what that entails, but they've at least gotten far enough such that they are building a web-based tool for code browsing and more [1], so it appears they've made some effort to decouple the Swing GUI from their underlying platform. I'm not sure how much of this can be seen in the open source IntelliJ Community Edition or where it stands, but maybe something similar to NRefactory (what Omnisharp uses for C# support) can be achieved.

BTW I've recently tried omnisharp-emacs, but found dealing with larger C# source files was way too slow to be useful. But it's pretty great to be able to use Emacs for C# and get useful code completion, so I'll be continuing to make efforts to make this work.

I'm using Omnisharp extensively but I don't have to deal with large C# files so I've not run into any issues there. I try to keep the classes and methods small and clean so I hope I continue to not run into issues there.
