In theory you can do this. First, set the transport stream id,
network id, and service id for the channel on the non-EIT source.
Second, check the "Cross Source EIT" checkbox in the EIT Scanner
options in mythtv-setup in the General section. I've never used
this myself, but this feature was implemented by someone with
a DVB-S setup where one transport provided the EIT for all his

Yes, Janne is currently working on this. It's a pretty large job
to get this correct for all the different EIT sources and we've
been slowly adding all the pieces for this to work properly over

I have no idea, I've been using DataDirect for a while now.
I only use XMLTV when testing modifications to mythfilldatabase
so I don't know much about the details of how XMLTV works.
My guess is that it will only insert data for channels that
already exist in the database so bloat will not be a problem.
