i dont think it will work. there is too much rocker in a wakeskate. also the flowrider boards have an assymetrical rocker similar to a skim board were the tail is almost flat so it is fast enough. the flowrider boards are also narrow and taper quite a bit at the tips so you can go edge to edge the flex also helps. a wakeskate would be really hard to edge on a flowrider because the width would not allow it to roll over.
just use the flowrider boards they are so uch fun and they dont limit you. but the first hour will definitely kick your butt.
