Hasbro with marvel legends around late to 2014-2015 they gave swap-able heads to some characters whether it be single carded exclusives, some figures that are kinda civilians i.e shield agents etc.
I think they are releasing an MJ okay shes not a hero but a civiy as for alter egos within marvel i think Peter Parker as more of a chance of being sold as a single figure. I think the most recent was bruce banner which was part of a 4 pack

i remember DC releasing, i think 5 or 6 pack of batman figures one of which was bruce wayne in there for the arkham series.

In general i think alter egos figures might not sell well, that's why you have 1 or 2 in a set rather than a single figure in a wave, thinking of having a wave of alter ego figures that just look like civilians might be a huge plus for us fans, where as kid which is i think is their main target audience won't want an alter ego figure, spider-man would be more appealing to them rather than a peter parker figure.
