Great writeup, and I understand the concerns about FT8, but I'll reinforce what Mike says a bit with an exchange I had with another rover when I was in lonely DM83.  The attempt ultimately failed because he apparently couldn't hear me on 2, much to my disappointment.  Clumsy, inefficient, yes.  But possible, and still fun.
