That's my thinking as well, although HT may just go all-in and ride the Endgame popularity wave for all it's worth. What would they have to change on the CM suit - the shoulders? Couple that with a rooted version of the existing head sculpt and they're done. Pretty cheap from a development cost standpoint. I'm not ruling it out just yet.
Rooted version. I hope they don't take that backward step but if they do then this Captain Marvel will skyrocket in price.
