There are already good beatsaber avatar worlds
What you want is to have unique songs and beatmaps instead

And maybe make a beatsaber world that utilizes the auto-refresh poster that streams an image for your beatmap from an external website while using the video player to stream in the song.
This would make it so you can have an infinite amount of songs and beatmaps all within vrchat. Essentially killing beatsaber(facebook)
