You're not taking into account the wishes of the girls. Xenovia, Asia, Koneko and maybe even Akeno herself will want to join Issei's peerage, since they already love him. And do you really think Rias will risk their displeasure by refusing their wishes? And since when has Issei ever stood up to those girls? If they want into his peerage, they'll badger him until he accedes to their wishes. No doubt about it. Issei won't stay Rias' pawn once they're married and he is a King in his own right either. That makes no sense.

The alternative is that Issei forms a peerage of up to 15 people. Most, if not all, of which being females and part of his harem. I say 'part of'' because his harem will also contain ALL of the females in Rias' peerage as well. Plus extras like Irina and Le Fay. This could potentially make his harem HUGE and pretty ridiculous. I'm not saying it won't happen, it just makes more sense to me if his harem and his peerage are one and the same, with no extraneous members. With the exception of his (future) wife Rias, who doesn't count as a harem member anyway.
