Please try to explain what exactly is your problem, using unit-types like void seeker may become a problem as soon as someone doesnt know which unit is meant, the void ray and its movement boos technology, or the void seeker, the ship used by zeratul in the campaign?

if you want a lasting movespeed bonus on the charge ability: just change the duration of the zealot-charging behaviour to -1 and remove the validators on the charge and disable charging effects and the charging behaviour
