You mean like the Google Ventures-backed Apportable[0]? It's already delivered 3 of the top 10 games on Android, and I'm currently using it to port a "normal" social network app from iOS to Android (using the development version which re-implements Core Animation on top of OpenGL ES 2).
And getting back to the Oracle ruling I think the fair-use defence for something like this aimed at a compatible implementation would be stronger than Google's because they were trying to fork the platform and avoid the available Java licensing offers.
