So, the tornado, hobie wave, and taipan have all had luck with the chupacabra\code zero\hooter\upwind gennaker. What other classes have been able to pull it off?

I frequent inland lakes that often have light and shifty air. 4-8 knot winds are not uncommon. Could I pull it off on a hobie 16?

More importantly, could it be pulled off on a Mystere 4.3??? And would it be class legal on the 4.3????? Yeah, I'm thinking about buying one.
