Should some banned weapons that relies on gimmicks based on alt-fire (i.e. Soda Popper and Cow Mangler 5000) be restricted instead?

So, let's assume a weapon is banned because of a certain gimmick toggled by the alt-fire. If we make a rule that makes the said weapon be used but cannot use the alt-fire (as in, unbind the button if using the weapon or being punished for using the button), would it be a good idea to make it as a rule? It could create some variety in gameplay whilist not making it too broken (Soda Popper for being a Scattergun better suited for burst damage and the Cow Mangler being a situational sidegrade to stock). What do y'all think of this?
