Everything you are considering would make a wonderful/spectacular surround system. I really would go for the MC402 from what you are saying. Programing becomes the key here. How many BD/DVD discs with more than 5.1 discrete channels will you be playing, right? Is it worth the extra expense? Your pre/pro will combine any extra discrete channels into your existing system anyway.
I checked out the Atlantic Tech Speaker system you are using and they are very impressive. Happy Listening.
