Bizarre question that I didn’t know who to ask

I was recently gifted an iPod classic 6th gen, and I love the thing, but being the type of person I am I want to modify it. Keep reading this is relevant to this community I promise.

There exist many boards that would make this easier, but there is one feature I’d really like to have- ecosystem-level compatibility with AirPods. Full audio quality, intelligent switching between devices, etc. Something I’m wondering about- is there a microcomputer decent enough to run macOS, even a version from years ago, so I can access these AirPods features without as much setup? I imagine there may be a simpler solution, if anyone can point me to it I’m all ears.
