If you are going to put in a valve that only supplies one at a time, why wouldn't you just not turn both of them on at the same time?

I may be missing something here, but you seem to be overcomplicating this issue.

Yeah, the worst case scenario is you forgot, try to run both, but don’t get full output out of either. No worries if you simply just use one or the other at a time.
