For a bolt on wing I believe you recommend a dowel peg on the LE with the bolt on the TE. What about using two bolts, LE and TE, instead?

This should work fine as long as you have an adequate place to put the forward bolt. The problem is finding a place to put the hole without destroying the structural integrity of the A ribs, the leading edge or the spars. The center section sheeting also isn't strong enough by itself to carry the loads. Probably the best approach is to fit some 5/16" balsa sheet doublers to both sides of the A ribs between the spar and the leading edge. Sand them to match the curve of the sheeting on top and bottom before you apply the 1/32" sheeting. Drill the screw hole through the middle of the A ribs between the spar and the leading edge dowels. The balsa doublers will replace the strength lost when you drill through the A ribs.
