It can easily be curved if you have access to a forge. Actually, you can probably do it with a torch. Use a wooden mallet or a 2X4 as the hammer and a piece of 4X4 as an anvil. Heat the blade up to medium red color and gently strike it along the spine with he edge resting on the wooden anvil. Be gentle and coax a little curve into it. After the curve is right, check for any twist or warp, and heat again to straighten if needed.
For sori, rest the tip on the wood while working the spine. For recurve or drop, rest the edge at the center or toward the ricasso. You can hold the tang with hot gloves ( it does not need to be heated ) or use tongs or vice grips.
If you have a friend who is a smith,he can curve your blade in a few minutes with his forge, anvil, and a light hammer.
Because you don't have a filled out profile, no one knows if they can offer to have you come over to their shop and help you do it.
