I really doubt they would though. The whole idea of this "harem story" is that these women are so obsessed with Issei they "tolerate" him having other women. That's how harem stories work. In other words, it makes no sense for them to be fine being a part of a harem, which is inheritently demeaning for women, just to date other guys in the same fashion. These women are so invested they take him anyway they can give him. Some of them even contemplated suicide when they though he died, just to be with him again. Girls like that don't date around, even if the guy is okay with it. Also, some of them are so emotionally invested, like Akeno for example, I feel they would shutter at the very thought of upsetting him over anything. Akeno's basically entire world revolves around Issei, so I don't even think there is space for other guys.
