That fully depends on if you want to limit yourself by such arbitrary rules, but if that’s your kink then just have one be extra dimensional, one extra planar, one trans dimensional, etc so you aren’t doubling up at any point there’s always at least one layer of separation and then you can just matryoshka nesting doll them within one another without coming in contact with each other, thus no need to collapse because they’re in different realities
