I've had worse that worked rings look ok you have nothing to loose by trying.

I'd take a tree radius in a die grinder and feather that big gouge in the crown so it won't be a hot spot, and smooth out the dings on top and along the sides with a scotchbrite roloc disc. What kind of shape is the cylinder in? Probably has one pretty good groove in it from the looks of things.

If it was me, I would fit a new piston & rings. That piston is likely to fail also crankcase vacuum would be reduced considerably and that will affect engine performance
If it's worth doing, do it properly.
