Hey, as long as we're working on weird, non-traditional perversions of the natural world, here is a page of “Afro 6” groove in 5. Or 15/8, which is a triplet feel in 5.
This groove in the original 6/8 is one of my main means for understanding the world of rhythm, drumming, and the drum set. I work on it a lot, and it influences my playing even when I'm not playing that groove. So naturally adapting it into 5 will help my playing in 5 more broadly.
Learn to play the entire page without stopping, then drill it with my stock left hand moves. You could practice it with this cheesy loop sampled from the Jesus Christ Superstar OST.
