I've been hoping for basically the same thing. That said, putting any new language on top of Roslyn (not just using it for IL generation, but actually making it a proper provider a la C#) is 1) not supported, and 2) not seeming like it's going to be. I have a language on .NET that I would love to build into a first-class Roslyn provider but there just isn't any support for that right now. Maybe F# folks inside MS can work to change that.
