I have found that any kind of Bryce file can be swapped back and forth between B5 & B5.5. Scene files, mats, skies, etc.

I have Bryce 4.0, 5.0, & 5.5 all installed on the same drive, no problems at all. I've even had them all up at once all working/rendering.

Yeah, get the latest B5.5 patch. I had a few crashes before, but ever since B5.5c, smooth sailing.
