I don't think Mike would mind. Be kind of fun. I flew an old trainer and a Goldberg Cub with floats some years ago in my home town pond. Sure did make the geese hiss when that big yellow chicken hawk came flying by.
Heck, I think Ken Willard had a little single channel 1/2A water plane design at one time. Seems it was on the cover of one of the magazines. May have to did her out and take a look!!
