You'll want to read the post dated 2-19-09 in this thread, by the noted designer Steve McCormack. Among other things, he makes a strong case for why vertical biamping is generally preferable to the horizontal biamping arrangement you are contemplating.
Re the bridged monoblock possibility, if you don't necessarily need the added power capability that would provide, probably the only way to judge is by listening, as was suggested.
As you probably realize, bridged mode will cause the amplifiers to see the speaker impedance (6 ohms nominal, 3.7 ohms minimum at 90Hz) divided by a factor of 2 (in other words, the amplifier would see 1.85 ohms at 90Hz). Your amplifier can certainly handle that, but it would stand to reason that the character of its sound might be affected by that difference, in unpredictable ways.
Also, in vertical biamp mode both channels of each amp are amplifying identical signals, while in monoblock mode the two channels would be amplifying signals that are inverted internally, relative to each other. Again, hard to predict what the consequences would be, but it stands to reason that there would be consequences.
