Lastly, leaving a passive crossover connected and bi-amping pretty much destroys all the advantages of bi-amping anyway. However, if you going the passive crossover route I can say that bi-wiring has no advantage at all over just using a properly gauged single run of speaker wire.
My main point, anyway, was that bi-wiring would be just a waste of wire.
