DOHC intake manifold on SOHC? possible?

Guys,

Still looking for a roots or twin screw supercharger I came up with the idea of puting a complete Cobra Intake manifold with stock blower onto my 2000 GT SOHC. They normaly go for pretty cheap money on ebay.
Since I was never a lucky guy who had the chance to compare a cobra intake (dimension wise) to a GT intake, I am wondering how much machining would be required to accomplish this task.
Has anybody ever done/tried that?
What mods, welding, millig, etc. was necesary?

Any input is appreciated
