SX/SXi/SXi Pro Impeller worth sharpening?

[RabiitPHS]

I just bought this ski and it looks like a rock was thrown around in the impeller for awhile. Can this impeller be sharpened or is it a waste of time? How can you tell?

Doesn't look that bad, you could sharpen and clean up those leading edges and check for any bends if your on a budget. Impros can rework it for 100$, or buy a new one for 2-300$
