I've seen this topic hotly debated since wizards came out with this UA. No matter how you think they may or may not work with each other mechanically, (either cursebringer not be restricted to a greatsword, or hex warrior apply to 2 handed weapons, or cursebringer turned into a class feature etc.) Should they? I encourage everyone to discuss their reasoning for their vote in the comments. I personally can see good arguments from both sides.
Your vote: yes
