The one big concern I have with this theory is that the new trilogy seems so prepared to divorce itself from the EU in order to open up the story possibilities. Will all of those CLONE WARS shows be considered canon, and something that could impact the movies? As annoying as the whole "What's canon? What's not canon?" issue has become, I think this is one area where it bears some examination.
I thought that when they announced what was considered canon that they said The Clone Wars cartoon were considered as part of the new canon now. As well as Rebels.
