Yes solely providing the primer pairs do not interact.

Probably, but only if the primer pairs amplify their targets with the
same efficiencies and that one primer pair does not out compete the
second pair for reagents. That would mean that the product bands for
each target should appear at similar cycle numbers. A bit of work will
need doing to check this out before you rely on the result.


The problem with being on the cutting edge is that you occasionally get 
sliced from time to time....
