"I went to eat with him one time and described the Final Fantasy VII universe in rich detail. And it turned into this process of collaboration, creating the character together. Then we went to the studio and recorded the Japanese voice with all that in mind. So he really was a creative partner in all of this. And we really wanted the connection between Dirge of Cerberus and Crisis Core." - Hideki Imaizumi, the producer of Crisis Core.
"Imaizumi and Gackt came up with Genesis's design, describing everything from his attitude to his clothes" according to the wiki page. Again, it's not damning evidence that he had a part to play in Genesis' ultimate role - but I don't think it was wholly SE's idea either to suddenly have Gackt's insert character so crucial to the plot of the original game. It was all Imaizumi, who - to my eyes - basically added Genesis in as a blatant example of a Mary Sue character.
