Twin engine vs inline flywheel supercharger idea?

[Roberto palacio]

Had this idea today in my garage when I was setting up timing marks on the crankshafts and flexplate,the front engines flexplate would not be spinning the transmission.The flexplate is 14 inch diameter could you weld a series of fan blades to the flywheel face, get a modified bellhousing create an air tight seal to create a "blower" to feed both engines to a common plenum box.Not
Looking for high boost numbers maybe 3-5 psi,most likely would only occur at high rpm.

Need to change post to utilizing flywheel as a blower/supercharger

I seriously doubt this would be a useful method for compressing air compared to just installing a purpose-build turbocharger or supercharger.
