Before building any physical diffuser, I'd run it through CFD software. You can often find engineering students who have access to it, if you don't know anyone in the real word.

I suspect that due to the engine you won't be able to have a smooth enough transition through the diffuser to prevent flow separation and thus have no downforce effect.
