I'm not the person you replied to, but if you get a monitor arm made for an ultra-wide monitor, it will be longer and taller than most.

I use this one myself: https://www.amazon.com/gp/aw/d/B00B21TLQU

It can go far taller than I need it to, and the length of the arm itself should be enough that, positioned well, I imagine you could get it situated however you wanted.
