While I recognize that the Kendo Club are Anime only characters, I personally would love to see them, and Aika Kiryuu, become Issei' pawns. From seeing him as their peverted enemy to maybe reluctantly becoming his servants would be delicious. As for abilitities, their Kendo skills would be very helpfull, particularly if they were granted artificial sacred gears. Kiryuu, seems to be "gifted" in reading people (and other things), and would probably be the one to bring the other girls over to the dark side, as it were. I personally see her with an artificial sacred gear based on a Yuki-onna, using demonic magic to do more than just having a frostly breath.

Chances - virtually nil, but it could be fun!
