Yes. I wonder if there is such a thing as a post-amplifier mixer...

You could use the outputs of the power amplifiers into a passive mixer
with suitable attenuators and then feed into an external amp. I suppose it
is possible to make a mixer running at LS level using transformers, but
I'd guess an expensive option.
