As far as I can see, the class rules neither allow nor disallow changing hulls. Not that I've read the whole thing, but I suspect the IYRR doesn't say either. If I were you (famous last words), I'd ask the race committee/organizers of your regatta as much in advance as possible. If possible, ask them to spell it out in the SI. I can see the committee being less than happy about having to measure another hull and spars.
Curiosity killed the cat question - what are you asking? I've only heard of folks switching hulls in 3 situations: Broken boat (obviously), they're flying in from somewhere and chartering, or the regatta specifically forces everyone to swap hulls between races so as to even out any advantages.
