I think most aquarium plants will grow emmersed given the right environment and enough time.
I think I've heard before that anubias are common in their native territory on waterfalls and such.
I think any of the hardscape plants (anubias, java fern, bolbitis, mosses, etc.) will gradually grow out of the water if you let them, but I have limited experience with this. Probably easiest to attach them to the wood just below the water surface, and let them grow on their own. It will probably take a bit of time though. Having a misting system (or regular manual misting) might help, but I'm not sure.
