The girls won't be dating each other prior to entering Null's polycule. People forget that's why we don't use the word harem. You're not just dating a bunch of girls. By entering Null's polycule, they're dating each other as well. That's the primary reason the girls have to like each other.
Satellite members are a thing IRL. Where someone in a polycule dates someone outside of the polycule and that person doesn't join it, but as myself and others have said. Let us cook. 1.1 is a bit away and we still have plenty of systems to work out.
There are a lot of dynamics with polyamory that we're exploring when it comes to writing. There are several "friendships" in the comics that the writers have stated that if the censors didn't stop them, they would have put them in same sex relationships. Claremont tried to have Kitty hook up with both Magik and Rachel. So we may do something fun with those set ups that sadly were never executed.
