Ideas for companions with the new subclasses?

With patch 8 dropping "any day now", I was thinking which of the new subclasses would have fitted the companions had they been out when the game first launched.

Swashbuckler almost feels made for Wyll, if it wasn't because of that pesky pact.

Giant Barbarian would gel perfectly with Karlach and her fire theme thanks to the lvl6 ability.

Shadow Sorcerer probably fits better than storm for a "default" Dark Urge (or as fitting as anything I guess)

Hexblade Warlock is another that would probably make more sense with Wyll had it been out at launch.

Death Cleric would have been good for Shadowheart and her emo+goth gal extraordinaire vibe.

Any other cool ideas?
