Playlists management on Mac and iPad with files on external HDD

Before i buy the new Version of djay on my Mac i want to know if i can do this:
Use an external SSD for all my (iTunes) Music and sync this drive to another external one. Then manage playlists within djay, not iTunes. When i plug the drive (or the clone) to iPad or Mac, do i have access to the playlists and can they both, mac and iPad find the linked music files reliably? 

i strongly +1 this idea !

I don’t know if this is actually an “idea”, because we have already all preconditions like icloud and external drive support in iOS 13. It’s just the question if algoriddim do make use of them.
