So what do you think is it possiable or just a dumb idea?

Kia ora Tony,

Not a dumb idea, particularly in view of the paper you introduced in the throttle body thread. However as pointed out there, at the engine speeds and valve timing you are working with, not altogether practical.

You are involved with a situation where several induction and exhaust tracts are of necessity, arranged to take advantage of gas movement occurring in adjacent cylinders, and therefore all six must be treated as part of a single system. A single detached cylinder would involve quite different parameters. You are stuck with the cost of a six pack.
