Welcome to the Rockbox Technical Forums!
The main problem is RAM size. Rockbox needs more then 2MB of ram (I'd say 4 is bare minimum). Ah, and porting to new architecture (Xtensa) is *a lot of* work.
I too have toyed around with building a RB capable player.Unfortunately, it is really hard to compete with economies of scale.Even at the $8 price tag for that board you are forgetting about all the ancillary devices that are needed.Off the top of my head.. Screen, DAC, amplifier, battery, charging circuit, buttons, case, and whatever else I might have forgotten.IMO in then end you are probably better off buying a ready made solution.

Yeah ... super cool ... did Rockbox ever get a linux port that could easily be put on the Zero?
If I were looking for a solution to this in the year 2018, I'd use a Raspberry PI Zero W:
For RPI 0 there is some points that might need to be considered. - Screen might be a problem. - ower comsuption - Sound quality
Ok .. so also .... just found thishttps://www.aliexpress.com/item/UGEEK-ZPOD-High-quality-lossless-HiFi-music-player-192k-24bit-Build-w-Raspberry-Pi-Zero-Portable/32790282017.html
Will ir run on a Ras Pi ... and then ... will it communicate with he touch screen or does it need button inputs to be written into the code?
