Well, the Eurocopter NH-90
, aka the "MRH-90", is an actual, relatively cutting-edge military helicopter. It has a form which borrows a little bit from the Bell 222/422 designs, but is a lot bigger.
An ex-girlfriend of mine does (or did, have no idea any longer) work for an Australian defense contractor that dealt with them. As I recall, she was rather proud of the thing. She also turns wrenches on both rotary and fixed wing aircraft, so I guess she'd be in a position to know if something was worth it.
Anyhow, regardless of what airframe they'd use today, 80s Airwolf is a genie loosed from a bottle which can really never go back. I don't think anyone these days would buy into putting turbojet / afterburner engines on a helicopter. BUT... and especially if Andrew Probert could be allowed to put his hand on the thing, I'm absolutely certain NuAirwolf could be made to look utterly amazing. Frankly, it may not take a whole lot of effort these days, given the nature of technology actually already in use (flat panel displays, touch screens, general miniaturization, GPS, etc.)
Personally, if I were producing such a series, I would try to do a design as close as possible to a high-end version of a modern surveillance/combat chopper.
