Given that virtual tuners were already built to solve this problem,
the myth devs probably consider a solution to your question as a
corner case.

So you might want to consider hacking together a script to "tack on"
the overlapping portions of the 2 recordings which you wish to have an
overlap, after the fact. The earlier recording gets say 15 minutes of
the later recording tacked onto the end, while the later recording
gets 15 minutes of the earlier one one the start.

Have a look at the doco for the python bindings, you should be able to
get all the recording info you need. (don't forget to update the
start/end times in the database after you're done!)

For best integration with myth you could consider making it a user job.
