I suggest just using what is on the original plan. I also suggest cheating a bit and going for a bit more span with a bit more tip chord. The original wing is so severely tapered that I think it is a stall/snaproll waiting to happen at any moment when built as small as you are considering. At the Reynolds numbers your wing will have, I think you won't gain any practical benefit from trying to optimize the airfoil. Good luck.

At least make the tip chord larger. As PeterH says, the Rn is so small the airfoil won't be a factor, but it will be a tip-staller.
