I think the ideal would be something like a Xilinx offering, tailoring the CPU- regarding cache, parallelism and in hardware execution of hotloop components, depending on the task.

Your CPU changes with every app, tab and program you open. Changing from one core, to n-core plus AI-GPU and back. This idea, that you have to write it all in stone, always seemed wild to me.

I'm fuzzy on how FPGAs actually work, but they're heavier weight than you think, so I don't think you'd necessarily get the wins you're imagining.

You should definitely look into AMD's Instict, Xynq, and Versal lines, then.
