I think the perfect example to this is simple this is this and that is that. Plus it just doesn't work with the story and I think your forgetting how many stories there are where the main character has a wacky or funny sidekick, friend, class clown and etc. It's a very common and most of those stories they don't get a real spotlight other than being a side character and no offense, but I don't see those two as main characters. I can see a plot where Issei tells the truth,  saves them, but that's it. Kind of how Issei's parent found out and their relationship with the supernatural. I think your going to happen to give up that idea of yours because I'm pretty sure you alone or a very small portion of people will be disappointed because it's not going to happen. I can see Kiryuu being reincarnated because she's female but also cause of her relationship with Issei and the church trio and that she wants to  help, but that's it. Issei will become the Harem King with a peerage of women.
