Undercutting dogs?

One of my gearboxes was jumping out of 5th on a regular basis. I was wondering whether undercutting the dogs would be a good idea, and if so, does anyone know a good company that does this?

I would assume that Ellis Moore can do this. And yes, it is a good idea, especially for a race bike. But normally there should be no real reason for jumping out of gear if everything is OK, so perhaps something is wrong in the box, e.g. bent/worn shift fork, rounded dogs on the gear. I'd give the cluster a thorough inspection while it's on the workbench.

Nova Racing maybe :P

Would it affect the hardening on the gears though as the hardening is a very thin top layer ?

Nova are too pricey, MPE is the best bet.
