Has anyone tried replacing the SMPS with a linear power supply, as commented on in post #51?

Yes, see post #113 in this thread.  My xdm1041 has been running continuously on a lipo cell with wireless charging for the past 8 months or so.  I never turn it off and just pick it up off the changing base when I need to use it off the workbench.  No problems at all, other than the bugs reported above for version 2.xxxxx firmware.

I had already seen your modification, it was very good!
My idea is to put a small transformer and make a regulated power source. In this way try to escape some noise from the original switched power source.
