No, You Cannot Bi-Amp

The designers of these speakers do not believe that bi-amping is superior to the as designed implementation.
The .7 maggies have a series crossover that they feel superior to any form of biamping. Wilson from the start has always felt that a single amp gives the best overall sound. I have tried bi-amping my 3.6's but have always gone back to a single amp

Take the money you save on extra amps, cables, and jumpers and buy a nicer amp, probably with more power so you don't give up any dynamic range.

In my mind biamping is a 'teenage' phenomenon.
If one is good, two MUST be better.
Yeah a few folks are able, with effort to make it work for themselves.
In general it is a waste of time, if as much effort was made to have one amp work well.
The worst side of it is all the folks who know nothing about it wanting to do it as if it is some easy magic panacea.. Gee I could biamp,,Cool!.... NOT.
