Have I actually laid out what my issues with the weapons list in 5e is? It's both boring and long, with obvious traps in damage and functionality, and somehow also lacking in anything resembling interest. If you want to do a big long list of weaponry, you can do better by looking at one of the Warhammer 40k weapon lists, with all of its modifiers and finnicky bonii, or you can look directly at FantasyCraft, which takes great pains to make each weapon type distinct through the liberal use of feats and class features.
5e doesn't do either, which is why I always want to get rid of it. 5e isn't really a game about whether you should bring a sword or an axe or a spear, and I kind of want it to be.
So here's a little something inspired by much-maligned weapon speed rules in 1E.
