A Marvel universe, Earth-TRN454, is shown in the animated series Ultimate Spider-Man (Earth-12041) where Spider-Man is Spider-Girl (Petra Parker). It is revealed that this universe is gender-swapped and we are also introduced to several other characters like She-Goblin (Norma Osborne), J. Joanna Jameson, Harriet Osborne, Nicole Fury etc.
Looking at this, does Marvel have a designated gender-swapped universe in the comics as well similar to DC1? I couldn't find anything in my search and as far as I remember, I haven't encountered anything like this in the comics that I've read either.
PS: I'm not looking for the gender-swapped characters (such as Jane Foster's Thor).
1 In the DC multiverse, Earth-11 is a designated gender-swapped universe (Bruce Wayne is Bryce Wayne, Diana is Dane, Selina Kyle is Sylvester Kyle etc.)
