Don't even worry about it, 1/16 sheeting is thin but is still plenty strong enough. Whether your wing has any sheeting on it or not the vast majority of the stress is on the main spar. Look at 4* wing it has no leading edge sheeting at all. Reinforcing the sheeting (unless its already damaged) will just add extra weight. Your wing will also become stronger after it has been covered.
I always caried my SSE wing halves around by sticking a finger in the wing jointer tube and a thumb on the outside, and the assembled plane buy the landing gear never had any problems
