Bi-Wiring Center as a left and right

If you do that with a conventional amplifier, the result will be each of its outputs will be mono. If you do it with a balanced (differential) amplifier, you'll likely send the amp into self-destruct mode.

If the speaker supports biwiring, it will send one input to the woofer and the other to the mid/tweeter.  If you wire each to a different channel, you will get lows from one and mid/highs from the other.  Not a good idea.

Cleeds, yes, biwiring sends the same signal to each input of the speaker, from the amp, but that’s not what Kal (kr4) was referring to. He was saying, correctly, that "it [the speaker] will send one input to the woofer and the other to the mid/tweeter." And his subsequent sentences were also correct.

To the OP, I’m not sure exactly what connection configuration you were envisioning between the amps and the four terminals on the speaker, but none will work correctly, and many will risk either blown fuses, self-protective shutdowns of the amps, or damaged amps.

Not a good idea, as Kal indicated. Regards,

No, you're thinking of biamping. Biwiring sends the same signal to each. They are two different things.

No.  From the speaker end, it is the same thing.
