Is it possible to change YouTube's offline video path to an external
  memory path?


This is currently not supported using official YouTube App.

The location for those offline videos is something similar to below:


  Internal
  storage/Android/data/com.google.android.youtube/files/Offline/(system
  generated folder name)/streams


And more so, YouTube controls access to the offline file.

The permission is controlled on their server per account basis, to access those downloaded files.
