I think the easiest would be to make Alpha Flight into an animated series... at first. That way, it introduces the characters to a new market and allows their popularity to grow. Following that, introduce them as "side attractions" to either a Wolverine / X-men movie or maybe the next Deadpool one (he is Canadian after all). If the characters poll well with the public, do a spin off on Netflix.

It's the easier way and most likely the cheapest way to take it one step at the time.
