Yep, seems like overkill, but the only way to do it right. The Pass amps will hold their value too, so it's not like you are throwing your money away.
This is a common mistake made with multichannel set-ups. Different amps and speakers for the surround and center channels. It's no different than making your right speaker different than your left. Think about it.
Monarchy makes good amps. Not a bad choice, just different.
Another solution would be to buy a cheaper 5 channel amp and switch to your Pass amps for stereo. You would need to switch cabling though. Or, you could sell the Pass and put the cash towards a more expensive 5-channel amp.
