McIntosh MC207 Plus Krell HTS - What Would You Do?

I recently upgraded my 5.1 HT system, replacing a Krell HTS 7.1processor and Krell TAS (5x200W) amplifier with a McIntosh MX122 processor and MC207 (7x200W) amplifier. Speakers are B&W N802D (front L+R), HTM2D (center), N805 (rear L+R) and ASW850 (sub). I originally was going to sell the Krell HTS 7.1 and Krell TAS, then I got to thinking, and the fun started. I initially set up the McIntosh 7 channel (7x200W) power amplifier in 5 channel mode (no connection to the other 2 channels). Then I thought, if I buy two XLR splitter cables I could use all 7 channels and effectively bi-amp the N802D speakers. 2x200W into each front L+R speakers and 200W into the center and 200W into each of the two N805 rear surround speakers. Effectively using all 7 channels of the MC207. Sounds good to me in theory, plus I get to use all 7 channels of the MC207. Then I got really creative! Why not put the Krell TAS back into service and either bi-amp the the N802D front speakers and use the MC207 to bi-amp the HTM2D center speaker and single, or bi-amp, the N805 surround speakers. Another option, and this is getting stupid, why not bridge the Krell TAS, 2x800W, to power just the front L+R N802D speakers. My preferred option is to use all 7 channels of the MC207 and bi-amp the N802D speakers, single channel on the center and surround speakers. OK, what would you do?
