I'd start with 11-46 or 11-50t cassette. You will need new longer chain. Do your homework on 11-50t cassette as derailleur may not support it.
The original plan was gx axs upgrade with an nx eagle cassette and a chainring/crank change. I am simply not confident 26->20 gear inches will close that gap. In any scenario, I would be going slower than I was, but may be able to maintain the effort.
