Useful to try...
 

No clue if it has been even suggested yet (if it has I am sorry I missed it) but would it be possible to rig a button that trades out primary and/or seconday slotted items for another set? Mainly thinking that if I Dual wield most of the time but want to pick a fight with the best damage backstab I can muster, then I would want to switch to a One-Handed pierce instead of a dual wield pierce for higher DMG...

What do you all think? Or is it even close to being able to happen?

Not possible at the moment.

Additionally, from what I've noticed, your weapons don't have an effect on the damage of your combat arts. I haven't done a thorough test or anything, but I've used a variety of weapons and haven't noticed any change in the actual combat art damage when using weapons of different speeds.
