It has been discussed before. And, I'm sure more than a few folks are still interested.
The question of replacing R410A with Propane has been asked and so far,
I've only read one case where it was done. (And was very successful per a Youtube poster).

And there was a study done, where they changed the cap tube in an R410A system..(IIRC).
Experimental Investigation OPTIMUM Charge R290
So, it seems that R410A can be replaced with Propane, and maybe without any mods in some systems..
