No, You Cannot Bi-Amp

Sonic benefits:

Transparency
Dynamic Headroom is not jeopardised by either descrepancies of amplifiers or decreased input amplification impedance
Tonal balance

Negatives:

1. 2 cheaper lower powered amps can have more power than one nicer more pricey amp so there are limitation on available options that should IMHO be present in complexed speakers
2. If two amps are absolutely identical, the benefits could be identical to a single amp only with increased power.
3. Y-connector on preamp output may be necessary that decreases an input impedance of amplification again limiting the dynamic headroom.

Regardless,
It's not worth to rant especially the post that starts with

In my mind

Natural desire of being right even if being wrong very often is subconcious.
