Is this nib saveable?

Alright, so this is the EF-nib of my Lamy 2000. A certain not so smart person (me) tried to soften it up a bit, since it wrote quite horribly scratchy out of the box. A little too enthousiastically, I guess, because it seems to be flattened too much. ('Flat foot'?) The horizontal lines are now quite a bit wider than the vertical lines.

So this doesn't seem ideal, and it still writes pretty lame. Is this nib still saveable, somehow?
