Can we change the way Braum's shield works?

Maybe its just me, but I feel like Braum would be a lot more fun if he were able to use his shield more often. Blocking projectiles is what's really cool and unique about him, but the way he plays right now is less about blocking projectiles and more about getting his stun off. Could we maybe rework him so that his E was a toggle ability that just drains his mana like crazy while active, or maybe give his shield the same treatment that Kassadin's ult got? Really low CD but each successive cast doubles the mana cost or something like that? Or maybe he can store multiple charges of his E but he doesn't hold up the shield for nearly as long? Idk.

I don't dislike Braum as he is right now, but I really wish his gameplay was more focused around the gigantic shield he always carries around.
