All comments about how the rules would make this difficult are, of course, noted - but please remember I did specify that it was only hypothetical, I'm aware of all the restrictions, and I'm not actually planning on doing this - it's just that when we were talking about it in the club-house the choice of aircraft was the area about which I knew the least!
MLS, thanks for the info on the Wiplines. I have to admit to never having realised that it's possible to get amphibian floats to fit to common aircraft. I always assumed that Cubs, Cessnas and the like either had wheels or floats, but not both, and that amphibians are generally custom built to be amphibians from the start. So I've learnt something new from this thread, which is just why I asked the question!
Any more input welcome, of course!
