Is it possible to get rid of all the macros TO_FIXED, FROM_FIXED, mult, etc and replace them with a class with the correct constructors / operator overloads?

Then your code doesn't ever need to be aware of the special fixed point math and horrible syntax everywhere and everything just works?

Yes it can. I’ve seen it done properly only once though. You still have to pay attention to avoid overflows
