Yeah Splint, I think that’s the way to go.  Both legs are about the same at the bottom but the thinner one tapers significantly towards the top.  I think grinding the thick leg to have the same taper is the best way to go.  The tops of the cutting edges will be weaker than the bottom but the whole edge isn’t ever really engaged anyway.  It may alter the 60 degree bend angle but that not an issue either.
