New Maya Skill Idea

So, I was thinking and i had an idea for a new skill for Maya. In all the trailers, it shows her being able to make her phaselock explode, but we cant do it in the game.
My idea is that lets Maya do that. It could be that whenever she uses phaselock, pressing the action skill button while its active turns it into an explosion. The sooner the explosion is initiated, the faster the cooldown and the deadlier the explosion.
Is it a good idea? Post your opinions about it
