It's funny, because they left the Pike out of that attack, which presumes that even the designer felt that turning a pike all the way around was a step too far.
It's too far with the other weapons as well.
The solution is not to limit it to weapons that someone who doesn't know what they're talking about would think would work - the solution ought to be to change the fluff. There's many, many ways why any of that group of weapons (and, as
@Oofta says, many other weapons, and weapon combinations) could have to get an extra 1d4 bludgeoning thump in.
