I thought of the same thing. The scale retracts would definately be a problem, but you could fake it and use conventional main retracts.

The biggest problem would be the wing loading. I don't have the numbers in front of me, but you can figure it out from Lancair's website. The scale wing would be something like 500 square inches. On a 9 - 10 pound airplane that's about 45 oz./sq.ft.

Nasty!
