Plus mosses, baby tears, most carpetting plants. Might not be enough space for rotalas and ludwigia and hygrophila, most of which readily go emersed. Long root floaters like Amazon Frogbit and water lettuce are good candidates also, especially as they can take extra light / heat.
A word of caution: where wood breaks the surface is the prime area for algae, especially for BBA, even more so if in direct flow and densely planted. Just something to watch out for.
