How is this a bad idea? If there's anything that recent years have proven is that the best stuff happens in the Star Wars universe happens when one of two criteria is met:

1. Someone is around to give creative oversight to Lucas's imagination (the original trilogy)
2. Lucas lets other people run wild with the world (books, The Old Republic story line, etc.)

Pixar has done very well since the full Disney acquisition, and they've done a damn good job with Marvel (case in point: your own damned avatar and signature). Is nobody else excited that this could mean a good Star Wars trilogy?
