Two things:
1. There's so much of the "canon" that I don't like that I'm perfectly happy to disregard what I don't like and stick to my own imagination and the bits I do like for the rest. For example, the prequels occur entirely differently in MY Star Wars universe, and Greedo never got off a shot. People can disagree if they like. People can also suck it.
2. The EU can very easily unravel if you start taking away central elements from the earlier material. E.G., if Han and Leia never marry or have different kids, guess what! All that NJO stuff? Gone. The Vong war? Gone. The Corellian trilogy that takes place with the Solo kids? Gone. Same deal if you change WHO the kids are. Same deal if Luke has never married in Episode VII. You change that stuff earlier in the timeline, and you change everything that proceeds from that point forward.
Almost certainly LARGE SWATHS of the "canonical" EU will be eliminated with the arrival of Episode VII. There will simply be no way to reconcile what's in the novels with what appears on the screen other than to say "Alternate universe." Seriously. Get used to that idea now because it's gonna happen. The writers will not let themselves be hamstrung by 20 years of mediocre novels with a few excellent ones sprinkled in for good measure. You might get a reference here or there (e.g. "The Maw" Imperial weapons development facility appearing in Rebels), but much of the EU WILL be nuked. The amount of mental gymnastics required to make it fit will be simply impossible.
I advise you to adopt the approach I take: make your own canon.
