You could certainly do that if you have the space. In many respects that is the ideal--to have three identical front speakers, and it's what THX originally proposed. But most people don't have the room and are willing to compromise (it's not a huge compromise in my judgment) on the center channel for the sake of setup convenience. I'm assuming you'd have a pair of M60s or M80s as the main left and right fronts as well.
The VP150 at the rear center would integrate nicely with that kind of setup.
