I wish combat attacks and skill checks used the same math. Wielding a weapon is like any other kind of skill. Expertise for sharpshooter and expertise for grappling and expertise for persuasion, should all be the same numeric value.
It was a mistake to create two different systems.
I've brought it up before, but I don't see it as that big of a problem, BUT if one wants to have such a system just bring in Weapon Specialization for Fighters and Warriors.
I treat it just like a Rogue Expertise, but instead it is used for a Fighter with a weapon of their choice. In this they can double their proficiency bonus with a chosen weapon. If one wanted to extend it to other Warriors (Barbarian, Ranger, Paladin) they could...but I would NOT give it out to Rogues (they already have expertise in skills), Spellcasters (such as wizards, clerics, warlocks, sorcerers, as they already have their special bonus), or others who were not warriors.
Of course I don't see expertise breaking the game (and thus I do not see how weapon specialization of this sort would break the game). If one FINDS expertise to break the game though, this would also be likewise I believe. However, for those who don't believe expertise breaks the game I don't see any reason that this wouldn't be an idea to incorporate in regards to warriors/fighters and combat.
