Has anyone Modified Animated Blitzwings Cannons?

I broke out my Animated Blitzwing today and its just lacking something. I looked it over and man it bothers me that his cannons cannot move forward like on the show. Has anyone modified Blitzwing so that he can do this?

And if you have... can you give me some tips on how to do it?
