Might be bad in case of electrical failure. What about having two "opposite"
bleeder like valves, that when there is a pressure difference, one opens up
to equalize the outside, and inside of the floats?

I wonder if it would be possible to make inflatable floats that could be
deflated once in the air to reduce drag. Maybe a little electric air pump
to
inflate them again before landing?
