It sounds weird but why would a modern Fokker necessarily use a prop at all, why not a really small basic jet? A small jet would probably weigh less and by removing the prop from the front it opens up a whole world of options.

A huge issue with any open cockpit is bad weather, you could give it a enclosed plexiglass bubble cockpit like a Bell 47. Of course at that point you are pretty much obligated to use the Cobra logo and play their theme song during night raids.
