Replacement for factory water pump/case guards?

I'm planing on getting a new skid plate from Evotech Performance (http://www.evotech-performance.com/yamaha-wr250-r-2008-2013-silver-sump-guard). Has anyone found or know of something to replace the factory plastic water pump and case guards with? I know they make similar aluminum guards for a WR250F but I've had no luck finding on for the R. I'm not really a fan of big, 'all-encompasing' aluminum skid plates due to ugliness and noise issues. I do ride trails and I understand they provide better coverage, but the Evotech one will work just fine for me. I just wish there was something out there to get rid of the plastic guards...

I never found a complete, bolt-on, solution.

I got an Acerbis that looked like it would work and built the OEMs into it by using a coping saw.

Voile !







I cleaned up the edges with a dremel, smoothing them out around the bends.
