I can't think of any reason why you couldn't.
Probably stating the obvious, but without improved unarmed strike your unarmed strikes will still provoke and deal nonlethal damage, no matter how heavily enhanced.
I am not at home at the moment, so I could be wrong but I think that you will have to spend one use of Divine Bond for each attacking member. So, one use for each hand, each wing and so on. Of course, you can flurry with only one appendage, but I think that is not your intention.
