I have a WBBB and a Big Agnes. I eventually moved to quilts, just to try something new, but the wbbb/BA combo works great. My hiking buddy has the BA with pad in his eno doublenest and loves it. You probably won't want to inflate the pad all the way, so it isn't as rigid. The only couple of problems are shoulder coverage and zipper position. Your pad is only 20 inches wide, and you might get cold where your shoulders stick out and rub on the hammock wall. If you cut a piece of closed cell foam that is wider than your pad, and put it under in a "t" shape, you will be fine.
Also, it is a bit of a pain to get into a right-zip bag with a left-zip hammock like the wbbb, but it isn't a big deal. If your bag is a left zip, you are all set.
