Yes, it is a good idea and is probably feasible with some changes to mythtv.

mythtv-setup already has the capability to perform an automated scan and 
either apply immediately  or save it for later use, see 
https://www.mythtv.org/wiki/Command_Line_Channel_Scanner
However, as far as I can tell this automated scan does not work for 
DVB-S/S2, hence changes to mythtv.

I was thinking of something along the lines of comparing current channel 
setup with automated last scan and just identify something has changed, 
the user would then use mythtv-setup manually, to either rescan existing 
transports (with search for new transports selected) or import the 
automated scan results.
