good or bad idea?

Im pretty sure that won't do anything. You need to either take air from outside the case and blow it in or take air from inside the case and blow it out.

retarded idea

Minor problem of a metal plate in the way.
Try putting it the spot specially designed for a fan, with a grate to let air in/out, and screw holes to hold it.

id do that and all but the connector is about an inch short from the sys fan pins on the mobo

Depends, it's a good idea of you intend to burn a fan and make lots of noise in the process.

Oh I get it now, so your motherboard doesn't have any fan connectors closer towards the rear? You sure it's not on the section of the board where the video card is blocking?

You're better off just keeping it off; you're wasting your time putting a square peg through a round hole going that way. You can buy a 90mm fan with a much longer cable or just buy a 3 pin fan connector extender, those are cheap.

Spend 5$ on an extension you stingy fuck.
