TW, besides making your plane 1/2 oz heavier, I can't see how it would hurt. What I don't like about the idea is the mind set. What I mean is that if anything, look for ways to reduce weight while still leaving the airframe just strong enough for normal handling on the ground and those extreme manuevers in the air. With a design that has a lot of wisdom in it, it wont be easy to find ways to improve it.
