I can see an argument for making the prequels animated. Particularly in an "old fashioned" 2D hand-drawn animation style, it would differentiate them from the OT and could be really cool.
For the sequels, it seems like a regression. I'd argue that if ever there was a time to do a mix of CG and real environments, and do it well, it would be now. Though I would be 1000% in favor of a complete return to the film-making technology of the OT, as that would be such a nostalgic trip.
