A) I only know of one SS, the Disturbance of a Devil, that involves the Gender Gun (If you know of another, what is it called and where can i find it?)

B) I am speaking of a hypothietical scenario, in which Vali is changed by another nethod. Just becausce a toy created by Azazel did not work, it is not to say it is impossible for a Heavenly Dragon to change genders. Also, Issei not changing might have been the result of Ddraig not being able to tand issei changing genders and becoming known as the [Lesbion Oppai Dragon], not just being there.

C) Vali already had a potentail love interset in kuroka, but turned her down. As he only seems to care about battles (Or is into guys), as such it would seem illogical for a new girl to be introduced for Vali at this point. I mean, i smoking hot woman, that also loves fighting as well. I don't think Ishibumi (Despite his genuis) could come of wiith a better match for Vali.

D) Also, it seems unlikely that Vali will get off Scot free fro his actions in the KB, and being transformed into a woman is often used as a punishment in Greek Mytholodgy.

E) Even if he didn't seem to into the gender swap idea, he has chenged his ming before As Orphis was slated to die after resurrecting issei in Volume 12. who's to say he didn't think that Vali would make  a better characther as a girl. Also, it would fill in the harem role of [Guy turned into girl].
