Mod man W-2 ported for 360-1 rectangle port

Has anyone here turned the Indy mod man W2 into a rectangle port for the 360-1 heads ?
I called Indy and She said I could turn it into a rectangle port to match my heads for my blower set up .
I am kind of skeptic since I have not seen it done .
I would hate to buy one for no reason .
I wish they would make a Dedicated blower manifold for those heads .
Let me know . Thanks
