I will have to say no because even in fanon we CAN NOT go against the canon when it comes to direct relations to characters. Your character being Naruto's sister (twin or otherwise) is impossible as Kushina was already concerned about giving birth to Naruto while being a Jinchuriki, a set of twins would have exacerbated her condition and would have made her delivery even harder. If you would like to make fanfic like that, it cannot be on Naruto Fanon Wikia as we have to uphold the canon, and use it as a basis.

For example, an Uchiha clan member needs to either have a plausible backstory as to how they escaped the genocide or have a background of being created or a future descendant of the last remaining Uchiha. Things have to make sense or else there would be anarchy.

Hope this helps.
