If all jobs became dual jobs, how would you pair them?

[HappyHubris]

So SCH/SMN has been a unique beast for FFXIV, where players can level up simultaneously as healer and DPS. This mimics other MMOs that allow players to "dual spec" to allow healers or tanks to farm quickly and otherwise enjoy the DPS toolbox.

Let's pretend that Square Enix decides one day to make every combat job a dual job. How would you want or expect to see them paired? This could be due to thematic similarity, similar skill floors, or any reason that you fancy.

There are 8 non-DPS jobs and 11 DPS jobs, so some DPS jobs would require pairing or some trios would be needed.

Tanks: Paladin, Warrior, Dark Knight, Gunbreaker.
Healers: White Mage, Scholar, Astrologian, Sage.
DPS: Monk, Dragoon, Ninja, Samuri, Reaper, Bard, Machinist, Dancer, Black Mage, Summoner, Red Mage

My Picks:

GNB & MCH: Guns go pewpew.
DRK & RPR: 2 edgy 4 u
WHM & WAR & DNC: Mechanically relaxing trio for players.

Viper and Ninja being both dual wielding and Rogue like.
