Swapping 3.6 intake manifolds

[jmann20051]

I was thinking, for the 3.6 , why I can't swap intake manifolds with a Acadia? My idea was to move the battery to where the intake box is currently and set up the intake manifolds so that the intake tube never runs over the hot exhaust manifold(this making the air substantually hotter) like the Acadia engine. I realize the intake manifold is taller, but realistically does anyone think this could work? I would of course do a extrude honed job on Acadia heads and intake manifold.
take a look at the pictures:

Acadia engine specs:
GMC Acadia ( with dual exhaust ) 275 hp ( 205 kW ) @ 6600 rpm SAE CERTIFIED
GMC Acadia ( with single exhaust ) 270 hp ( 201kW ) @ 6600 rpm SAE CERTIFIED
