You really want to know what I'd do?
I'd decrown it backwards, with the innermost ring you marked running 1/2" wide down the center, and make a narrowish flatbow!
Or I'd smooth one side flat and make a quartersawn grain stave out of it, just to learn the skill, just because I've been thinking about it lately...
And I'd fail, probably, and destroy the stave and I'd have lots of orange shavings to clean up...
