The party of identical twins

Let's say that for RP-purposes, you'd have to make a party that was consisted of identical twins(always making 2 of each character, same race, class and proficiencies), what woul be your choices?

Only things allowed different are their gear, since you can't have 2 Croms fe. Proficiencies would have to be the same though.

Try to consider utility as well as roleplaying. And fun ofc.
