Your list is more comprehensive (though I'm pretty sure the Dalia-Penny threesome is DEFINITELY going to be a thing and it's likely going stem from their ongoing sibling rivalry to contrast the wholesome sharing that Lauren and Judie scene had in OIAL) but as I said in my post you've quoted, the pairings I've cited are based on what the story has been hinting so far, pairings that might not even come to fruition given Cari's comments on the subject...

I understand why he would say such, though. Threesome combos are well and good, but you still have to make them work in the context of the narrative, so IMO those whose pairings have been hinted so far will take greater priority over the ones with little to no development (i.e. Nancy and Nova, Annie and Alex, Penny and Alex).
