This is just me, but if I were living alone, I wouldn't mind having a 
single frontend connected to each TV in the house.  But as soon as more 
people are interested in watching TV, not everyone will always want to 
watch the exact same thing all the time.  In that case, a cheap, lowend 
frontend machine (like a Revo 1600) at each TV makes a lot more sense.

Another option, it sounds like you have a lot of spare computer parts 
laying around, you could take an old computer, and just upgrade the 
video card, and now you have a new frontend machine for another TV.  If 
the computer is big and loud, put it in a different room, and just use a 
long HDMI cable (or HDMI over cat5).

However, if you're dead set on doing it the way you wrote, yes you can 
switch resolutions with a remote control.  irexec can bind a remote 
button to execute any arbitrary command.  One such command could be 
xrandr, which lets you switch resolutions from the command line.
