Yeah I'd love for her to work with him, he has been posting some of their 80s demos on his instagram. I'd wish she'd go back to working with one or two producers an album in general. She had a 100 of them in Rebel Heart and MDNA, and they were a mess.
And I agree about Rebel Heart. The dance demo of the title track and Hold Tight demo 3 (or 4) were superior as well. I think the final album could have been shorter too, there are some fillers. But Devil Pray is one of the best songs in her discography
I really like Holy Water too.
