To be honest, I don't know many exercises in anything like the same vein; if lots of people were doing this sort of thing in high-profile ways, I wouldn't be writing, because I'd be busy reading everything else! I suspect that here and there, below the radar, others out there are beavering away, but this just isn't the sort of activity that makes it into our collective systems for publishing and promoting books. Also, the day job keeps my mind stuck in the past, and it's possible that someone who studies contemporary long-form poetry would know of more examples.
I can think of just a couple of recent things which might in some way be relevant:
Maybe worth looking into Anne Carson's Autobiography of Red. Verse novels are also very much a thing in the YA space, so there's that, depending on how willing you are to read about teenagers.
