I was actually looking at building a script like this. Have you found anything that does it already? If not, I was just going to make a small python script with readonly access to my Youtube account that pulls down my Watch Later video IDs and feeds them to youtube-dl on my NAS. Sounds like a fun Christmas vacation project.

There are multiple articles automating this task using youtube-dl. There's also a recent project called tubesync[0] that provides a GUI and advertises itself as the sonarr/radarr for Youtube
