Been thinkin' that turning the 2.5 into RWD would be a pain, so how 'bout if I stuffed a 4.6L V-8 under the hood & cherry picked a tranny to drive the rear wheels? Functional scoop or cowl to clear the slightly taller engine... Combining a cross member & subframe to support the thing would be tricky if I wanted to maintain as much of the front suspension as possible.
Be an interesting project though, wouldn't it....?
