Short of trying to record the exact same show at the exact same time
on two tuners at a time, I can't imagine this being a problem. Keep
in mind that this is the same problem that would occur if you had
2 identical type tuners.
Something has to manage that.
Stuff is going to get sorted out by priority and then assigned to
available tuners. It shouldn't matter if the guide data sources
are the same, or if the tuner types are the same.
MythTV already has to sort out conflicting priorities when just
managing a single tuner and a single guide data source. It has
to "do something".
That leads to predictable behavior even if it is just a side effect.
Ordering of the application of recording rules by recordid is one
of these. You can tweak this so certain types of (more specific)
searches will be done before other types of (broader) searches.
I believe that I have the same sort of overlapping configuration
you're currently worried about. It seems to be no big deal. It
was a little effort to make sure that the locals got recorded
off my OTA tuner but no serious crash+burn sorts of problems
