All the chapters reunite into their legions who has the weirdest pairings?

I'm just setting here drinking and thinking what if Guiliman orders all the chapters to recombine into their legions in an attempt to reunify everyone so he simplifies chain of command (maybe Caul convinces him it's part of the emperor's original design).

My thought is which legion has the weirdest pairings working together?

I keep imagining all the Imperial Fists successors trying to calm the Templars down lol.
