Should/could riot create genderbend skins?
If you don't know what genderbend means, it basically means switching the sex of a character. Jinx is now a male not a female, Lux is a male not a female, Talon is a female not a male, etc. I definitely think riot can make legendary/ultimate genderbend skins. They already do large model changes when making a champion skin (especially higher end ones) and new VOs are recorded for ultimate and legendary skins. Now it really comes down to -Could this make a statement about gender that riot doesn't want to make? -Would the community be accepting? -Does riot have some alterior reason to not wanting to do a genderbend skin?
I think it definitely could make a statement that riot does not want to make. that could or could not be an issue for them. I'm not the controller of how they want their PR so I can't definitively answer anything.
The majority of the community would probably find them interesting and cool, but a vocal minority could take major offense to the idea of a genderbend skin and cause an uproar. I don't know how this would go in the long run.
I don't know because I'm not riot.
What do you think?
.....riven would probably be rather simple,given she is clearly human with no blemishes or special ability's/augments that are extremely visible. examples being
of the Fifth Armor
you have
Cow skin
and now you have Star Guardian 
(Only female on that line of skins)
