That'll work! If there was a way to weld three 30mm tubes to each side of a standard mini-foot flange, I wish they would show it, as that would be the ultimate. Your concept is darn close.

There's too much talk about scavenging on this thread. Forgetaboutit. Pulse conversion is where it is at for big boost. Man, BMW re-did their V8 for turbocharging last year. Changed the heads, cams, cam drive, and manifolds just to get short turbo manifolds on the INSIDE of the V. Unbelievable.
