M75 Conversion

First post here on the vibe forums!
I was wondering if it was possible to do a conversion from a musser m75 to an m55? I own a musser 75 and from what I know they use the same bars. Do they use the same resonators? Does anyone make m55 frames? It would be nice to have an m55 or something lighter that would be easier for travelling while still being able to use the same bars/resonators if possible.
