Hide weapon instead of swap weapon?

I think it'd be pretty cool if as an elementalist we could have the "swap weapon" icon that actually hides your weapon instead of swapping your weapon.

Why? Because I think it would be really fun to play as an elementalist that appeared to be using only spells and not real weapons - it has always felt that the use of weapons for elementalist was more to align them with the overall gameplay system than it was for any sort of serious thematic reason.
