As far as I'm aware Hasbro have EXCLUSIVE rights to make Star Wars figures, this is why lego cannot make Lego Star Wars CMF.
HOWEVER, DC allow many companies to make DC action figures (funko release DC vinyls as do DC themselves) so a DC CMF line is still in reach.
On the marvel side I'm not so sure, I believe it's more like Star Wars as in the Funko POP! Heros line most of them are figures with a movable head but the Star Wars and Marvel one are bobble heads, I believe this is to to with the whole exclusive rights to action figures and stuff.
Hope this clears some stuff up.
