You don't want much do you !
Given that your two amps are ostensibly identical I think this one is actually fairly simple: the pre-amp should be the same on both amps so choose one of the two amps (perhaps the one that sounds best, call it Amp A) and run the first three cables to it as normal. Then with the last cables run
1/4" Output Left --> Amp A FX Return
1/4" Output Right --> Amp B FX Return
Make sure that both amps have the FX Loop turned on. It may be that with amp B that you need to hang a dummy patch cable out of the FX Send and/or amp input to make sure that the FX Loop turns on properly.
With your signal chain: if you want to use any stereo FX then they would need to come AFTER the FX Loop block. Also be aware of how routing works within the POD otherwise. See Meambobbo's gude here --> http://foobazaar.com/podhd/toneGuide/setup#routing
If you are using two amps that are not identical then I cannot see a way to do 4CM without external loop switching support. I will mull on it.
