FSR4 running on CPU AI accelerators (NPUs)

Maybe this has already been discussed, but I haven't found a single post about it. What's stopping AMD devs from creating an FSR 4 FP8 implementation that can run on their Ryzen AI processors? Like, the AI acceleration hardware is already there, and AFAIK, it's capable of processing FP8, so why not use it to enable neural upscaling on machines with a GPU that don't officially support it? Would performance be bad? Or maybe create an FSR 4 "lite" version that can run on the CPUs already existing AI accelerators?

I know not many of us have CPUs with NPUs, but for those who do, wouldn't it be a genius idea for AMD to create this version of FSR so players can enable it without buying RDNA4? The hardware is already there, in many desktops, being used to accelerate other AI workloads, couldn't it be leveraged to make FSR4 more accessible for gamers? If anything, I think this could boost their CPU sales, as I think many of us would rather upgrade to a modestly-priced CPU with NPUs that can run FSR4 instead of discarding perfectly capable RDNA2 and RDNA3 cards just because AMD won't play ball and give us the INT8 FSR4 version.

What do you think? Is this feasible? I don't know mucho about AI, but it sounds logic to me.
