I had almost identical issue on an EMP skin. Van's recommendation was to clean up the hole flatten it and add two new rivets either side.

This is not as big if a deal as you may think. Deburr this problem area so there is no chance of cracking over time. Dimple and rivet the correct hole location as normal and add an additional rivet in either direction as shown below. If you don’t like the idea of having a blemished part on the top skin it should be possible to add a replacement in with your wing kit.
