Two 1st-Person POV Characters -- Too Confusing? Yay or Nay?

Salutations all.

I'm having a bout of uncertainty pertaining to how I want to structure my fantasy novel. I have tried thinking about this quite a bit and part of me thinks third-person point of view would work best, but a much larger part of me yearns to write them in first-person instead. While this may be easier, I don't think it will read as well as the two POV characters will eventually end up running into one another for a significant portion of the story, and I feel that could end up being a very confusing cluster-fluff.

Essentially, there's going to be an assassin and a king's bodyguard and the king's going to die but they're going to end up eventually teaming up -- SPOILER ALERT -- at some point later on in the story. So not just running into each other, but... essentially merging into their own kind of journey.

What are everyone's thoughts on this? I'm kind of leaning towards the first-person only really working if it was one, single, POV character, but alas... I'm at a crossroads.

Any input is warmly appreciated in advance and good tidings to you all.
