I want to do a spiderman one after the current one I am on

I am thinking of doing a spiderman Fan fic and wondered if it has been done yet with him having a twin. The twin would be Ben or AKA scarlet Spiderman. No real details of yet but would be nice to see him with a brother.

@arthurkerr: Don't know for sure if it's been done or not, but it doesn't really matter. If you have a story you want to write, have at it. :)

Thanks
