[SUGGESTION] Legendarie's aura as infusion

Since GW2 HoT, we can find a lot of new infusions that grants aura. I think it's pretty nice and it would correlate with something I had in mind since the begining of the game. Now see, I have this hammer that I love so much (Mjölnir) and I thought " God it would be so awesome to have the Bolt's lightnings around me with this hammer.. ". I understand it is some special featurings for unique legendaries skin, and yet I still think it could work, to be able to craft them somehow (Not talking about footsteps, mainly aura) and implement them as infusions so we can have various legendaries aura without having to wear the weapon...Any thoughts ?
