You are talking instrument panels here, generally a non structural component so it's not a big deal. However, the practice suggests a word of caution if done on other parts of the structure. Barnaby Wainfan has an article in the latest edition of "Kit Planes" were he cautions the use of combining materials of different strengths. For example, adding carbon fiber to wood components can actually make them weaker due to the different stiffness characteristics of the two materials. For example, a weight supported by two ropes, each rope carries half the load. Replace one rope with a wire and the wire carries the entire load until it breaks. The remaining one rope is not capable of carrying the load so it beaks. Read the entire article in the November 2015 issue of "Kit Planes". Larry Flesner
