How to power?

Run a HT Sys. Run stereo for music. (Mac mini). Have two W4S amps, st500 and st1000. Just add'd mono sx1000. Have Sunfire tga w/ 5 chan @400.
All spkrs are set up for bi-amp. So. I've got five channels to feed, and 10 power outlets.
Thinking of removing Sunfire, use 1000's cross front and 500 for rears. Only to free up cab. space and reduce cab. weight.
Other thought is use "carvers voltage" on bass, feed top range 1000, center mono 1000. Then bi amp/ or not surrounds .. Thk n outloud, any ideas be appreciated
