Matt Trakker was introduced into the GI Joe toyline as Specialist Trakker. My one and only GI Joe Figure.

Personally I'd love to see a reboot of M.A.S.K I think if done right they could totally pull it off. They're kind of there already with the Stealth Force bizzo of the other movie lines. I'd like to see it seperate to GI Joe personally, only because I thought the movies were rubbish, but if Matt Trakker is a character and it spins off into it's own thing, I'd be fine with that.
