Is there ever any reason to have
both pumps on at the same time??

I think you'll find that most pilots like to have both on at low altitudes, as Paul mentioned.  I actually run both of mine all the time, except when I'm transferring fuel (because the extra return flow makes it hard for my transfer pump to work).  I'd personally like to find out about a pump failure when I check them individually during the run-up. 
 
The only other concern about the way you're going to hook yours up, would be if there is any chance that the other pump won't instantly produce pressure.  You might get a momentary loss of fuel pressure when you switch.  You've got that HUGE panel on the -7, so you can afford space for one more switch :-)
 
Cheers,
Rusty
