This is not etherchannel, this is more similar to stacking. Etherchannel by definition is the aggragation of port bandwidth by bonding the channels together. Simimlar to PPP. You can bond 2,3 or 4. What you have isn't very smart because of all of the STP convergence that would be required. The absolute best scenario in this case would be to stack the 3500's together and then do etherchannel to another switch, say a cat5000. This way you achieve a very fast switching backbone and still maintain almost gig to another switch. You don't want to sacrifice ports if you don't have to. Ports cost money there is even a formula, I don't remember is though. Hope this helps.
