All I can say is wow, you're hardcore.  I'm lucky that while my HDTV
stations are not all in one direction, almost all are one way and another
is close and in the opposite direction, so I can make it work with one
antenna.

I've been amused at how HDTV has taken me and other back to putting up
an antenna.   Still, I think a rotor (though you already have a fancy one
so this doesn't apply to you) might not be the way to go unless your
stations are all over the map.   I presume you've experimented with
how bad the multipath is if you just merge two different antennas, and
found it unacceptable.   It would be nice if the tuner cards came with
switchable coax inputs, so you could say, "use antenna 1 for this channel,
antenna 2 for that channel".  An extenal box to do that might also be
good, an cheaper and more workable than a rotor solution.

I certainly hope so.  You can configure in the setup a command to
do your channel changing, so could you perhaps wrap your blaster command
in a shell script that just does a sleep after commanding the rotor?
Or does myth try to change before the command returns?
