Yes, looks like a very good practice thing and example of what you can do w/pentatonics. I agree it'd work well for intermediate players or even rather beginners who need a challenge, yet interesting enough for probably quite confident players too. You should make an example of how to play a similar thing over different root notes as separare parts and then as all them combined maybe?
