Any reason why you can't just take a single file with one binary microcode appended back-to-back after the other (i.e. exactly what /dev/cpu/microcode accepts)?
You'd only be able to release that memory after all cores were brought online [and any microcode that did get used to update a core was copied somewhere else for future use], but that's hardly a big problem.
