I have had no trouble importing Poser still objects into Bryce if I use 3DS, one can even import them in a manner which allows for all the body parts to be textured and rendered separately. As for Bryce into Poser, the best bet, I think is to make a Bryce movie, a sky for example and play it as aa AVI in Poser, then have your characters do what they will as though it were a 'blue screen, that's what I do.
