how about getting a 4-space rack, going tuner-->sansamp--> power amp in of ampeg, and leaving the rest of that mess out?
it'll probably sound better in a real-world band mix, and you won't hate lugging a big giant rack around.
(the next step after completing a monster rack with all the compressors, maximizers, power conditioners and all that is usually to decide to pick up a micro amp head "just for the quick grab-and-go gigs", at which point the monster rack never leaves the house again

)
