An A/B switch should work, as long as it can handle the current.  I've been
using a similar setup with a THD hot plate.  Just be sure that (if your amp
is a tube amp) that you always have a load on the amp, whether it is from
the speaker or the emulator.

Are you sure your amp line-out is pre-power-tubes?  (I think) on my amp,
the line out is after the power tubes but before the output transformer.
