That'd be simple to implement.

Just use a vacuum switch to control the alternator - put it in the circuit 
between the regulator and alternator.

This was done with air conditioning systems in Ye Olden Dayes when the engine 
was puny and the a/c stole too much power (typically about 2 hp, oddly enough). 
The a/c was shut off at full throttle.
