I'd second the recommendations for Odyssey Aerospace or G-Sport's. Though you're not gonna do a whole lot better than the Hazards, at least for a back rim. You could definitely put something lighter on the front, but keep in mind a lot of lighter weight aero rims (Envy, Deviant) are also super narrow, meaning if you run matching tires the front will actually look narrower (Odyssey Aerospace is a notable exception, but it's only like 1.5 oz lighter than the Hazard). As others have said, lighter tires are probably the better route.
I will say, speaking from experience, super light wheels aren't always as nice as you'd think. There's a reason super light weight setups have been going out of style lately. I used to run Alienation Deviant (~11oz) and Delinquent (~16oz) rims with Premium RefuseResist and Alienation Differential (~16oz each) tires. Basically a very low rotating weight setup. It was great for accelerating and generally throwing the bike around, but I've found recently that my brother's bike which has very similar geometry, but heavier wheels rides a lot better. That extra weight seems to track better and is much more stable over big jumps (I ride mostly dirt).
That said I'm 25 lb heavier than you and like to ride trails so our use cases aren't exactly the same, but there's my 2 cents.
