Chances are what will happen is the resulting elevator trim will be obvious to the naked eye. It also might change as the plane's airspeed varies. Then again, you might not notice much at all after you get the initial trim worked out. It depends on how effective that airfoil was on that layout, and whether or not it was actually effective on the model.

Very often, scale models that faithfully duplicated the details of the full scale wound up not needing or not reacting to what the full scale had.

I'd say you face an interesting situation and little more. The maiden won't be any more dangerous than probably half the maidens we see in the hobby. There are a LOT of models, especially now with so many models being ARFs, maidened every day with far worse aerodynamic problems than you face.

I'd love to maiden your plane. And would put money on that sucker getting through the flight with only some dirt on the tires.
