Disc-brake steel?

Well they do take the whole load, but it's not quite like that if you know what I mean, because essentially there's nowhere for the disc to go, but yeah they do Side to side isn't too much of a problem, there's a pad either side pushing against it. You can definitely have a new centre made, and buttons, and have another rotor stuck on there, but serious dollars to have something made to a standard you'd trust your life with.

Don't worry about heavy, heavy is good... when you're talking about what amounts to a heatsink Put your money into good tyres, and replace them before they're totally toasted in the middle... best performance improvement you can make to nearly any bike

Who told you about my tyres? Hahahaha! Nah replaced the centre slic/commuter spec rear. If the disc is off say, a 600cc sports bike and the centre is the right material and the buttons are up to scratch, how hard would it be to design/mill the centre? Just same weight and larger diameter would be sweet. Mine has 300mm front discs, I guess there must be a few out there that would suit that are 320 or 340mm?

It's not hard, because you'd be paying someone else to do it for you... it would be money wasted though.
