1.4.4 The distance, at right angles to the mast axis, measured around and back to the same point is referred to as the "mast circumference". The mast circumference shall not be more than 0.500 m.

This is box rule 1.4.4 of the F16 class. It is not possible to make a wing with a circumference more than half a meter.

That's besides all the technical problems there will be in sailing behaviour, but it is always possible to have a try.
