I decided to keep my options open. I set up an emmersed set-up using plants from the previous scape (and some Marsilea), did a sort of layout, and used Aquasoil capped over some organic substrate. So, if I want to go back to submersed, all I have to do is fill it up and go.
I have the little crypts,
Anubias nana 'petite', some moss,
Lilaeopsis sp.,
Marsilea sp.,
Ludwigia brevipes, Needle-leaf Java fern, and a grass I have not ID'd yet and will now be able to ID once it starts flowering. (I think it is in the Fimbristylis family and it has been growing well for me submersed...so maybe something new to offer once it grows out.)
