No. It would make lightning come out of your suit.

The haste effects only occured when Weiss uses the lightning dust because it interacts with her semblance. Dust as a base object is pure elemental energy; they don't have fancy secondary effects other than what the element itself can do.

You could use an element to get more speed, certainly, such as wind dust propulsion. But lightning doesn't make things faster as a side effect, it electrifies them.
