I have done a little bending and I think what you want to do is possible.
Since cherry fibers are easier to compress than expand, you will need to have a strong metal band with very secure stops on the outside of the bend. Next you will need a strong form - two pieces - both inside and out that you can clamp the cherry and the metal band into.
Cook the cherry for about 3 hours and work fast when you pull it out - get it into the form and clamp it in with about 30 seconds. A helper and strong clamps are required
Leave the cherry in the clamps for at least 48 hours. You can expect some spring back but probably not more than 5% - you can adjust your form radius to compensate
Good Luck
