Not without some upgrades to the 40-2CD.  As pointed out on this 
reflector a couple of months back, AA6PW and I sat down with BOTH 
manuals side by side, and the XM model is a bit more robust than the 
original CD.  The tubing diameter is smaller which would require 
re-stepping the elements and beefing up...EVERYTHING.

But to answer your question; YES, it can be done.
