In a word NO. You will fry at least one of the amps if not both.

Why don't you seperate the woofer wires in the speaker and drill a
small hole in the back so you will still have the advantage of
bi-amping ? Just make sure of phasing.

You could concievably run the outputs through a crossover backwards,
but that is ridiculous, plus it will still present an abnormal load to
the amps. How they would handle it is unknown, and if the frequency of
the crossover doesn't match the frequency of the amp's crossover it's
likely to fry, plus it won't sound right.
