hailz,

I like how PLD has a main and off-hand options with "endgame weapons" and would love to see this adapted to some other classes.

Just a few ideas:
Archer/Bard - add quivers to the "off hand" slot (even if the model doesnt actually hold it in their hand, it's just on their back/hip.)

Rogue/Ninja - decouple the main/off hand weapons so off hand can hold a kama, or a curved blade.

Scholar/Summoner/Archanist - main hand book, off hand... Quill? Crystal ball? Reading light?
