I rather think Lego would work just fine!
In fact I hadn't even considered Legos.
If you were use the smaller flat base or cut one to size, and three columns of the single row Lego blocks.
Then glue a flat piece of styrene to the side of the top pieces, one with the "V" or better yet a shallow "U", the other two with a slight dish shape of the wing I think you would have it!!!!!
Good thinking outside the box Karl!!
