Hmm...I wouldn't think so. The plants do transition, but it also has to do with the waxy cuticle that covers the emersed form of plants. When in dry air, the cuticle of a plant is thick, limiting the water lost. When in humid air, the cuticle of a plant is thin, allowing more gas exchange. The thinner the cuticle, the better the plant will transition to submersed form, as the thinner cuticle allows more exchange between the plant and the water (water, CO2, light go into the plant; water, oxygen comes out of the plant).
However, as TLE said, it might not work. I'm assuming that between plants at 0% humidity (very dry), and 100%humidity (very wet air), the plants at 100% humidity will have much thinner cuticles, allowing them to transition to their submersed form much faster.
So many fish to keep, not enough aquaria.
