Future Classic makes a complete retrofit kit, yes—it's been on their E90 M3 for several months now
You can find more information
here.
Not only do you get to use more robust M14 hardware, but by moving to the F8X hubs, you'll save 0.74lbs per corner up front and 0.54lbs per corner out back.
FC has also taken the opportunity to upgrade hardware for strength and options the drill bit necessary to modify your rotor hats, should you aim to use OE brakes or non-Brembo aftermarket applications. Brembo (I'm sure some others as well) have provisions large enough to make no modifications to the rotor hat during the retrofit.
Honestly FC's kit is virtually the same price as if you would simply replace your bearings / hubs with factory E9X equipment...it's something to consider if you're close to your replacement interval IMO, which I think a lot of E9X owners are coming towards anyway.
