Proposal: On Syndra's Q

I was thinking about Syndra and her Q, how when you use your q and e combo, it stuns, right? but you have to always w the ball, or w a minion, and the next q is 2 seconds later than any engage you might have had. Say the enemy goes in since you've wasted all of your cooldowns. Your q is useless because it's hard to hit when they're coming towards you and stuff. Your q is basically useless in terms of damage not only because it was recently nerfed to shit in early game exchanges but also because you only get to use it for the q e combo engage. You're left with your w for your main source of damage until about rank 3 Q.

So what if you made syndra be able to hold more than one q at a time, like Vel'koz w, or Akali ultimate. I'm thinking three would be stupid, but 2 seems just about perfect. With the recent nerfs to her Q, maybe this would put a slight buff on Syndra's Q without taking away the whole purpose of nerfing it in the first place. It's still hard to hit, but at least you get to use the 50 ap damage rather than just using it to set up for your combo.

I think a half to 1 second delay between stored Q's would be appropriate, much like azir's W, About the time it takes for Nidalee to jump after she gets her reset.

So what do you think, would this be cool? or not cool? Balanced or Extremely overpowered?
