I have that gauge set but I left mine as it came. I think because of the radius around the gauges, you would have to cut the decal larger than the openings and the black plastic would show. For that reason I left mine as is.
There is a water transfer hydroprinting of parts but I am not sure how you would keep it off the outer bezel.
I believe they spray a clear over the hydroprinting to give it some protection. I actually looked into this as a side job once but I don't recall all the details. You could ask them if it can handle masking tape and if so I would mask off the part you want and you could spray whatever color you want on the outer bezel and make it look pretty close to original.Thanks, think ill look into both options suggested
