In my experience, crypts have worked very well as "dry-startable," non-carpet plants. They love growing emergant, put out extremely impressive root systems (which I believe is key to DSM success, right?), and transition well to a flooded tank. These are non-c02 and low-light compatible. Parva would take a long time to "carpet", but works well as a fore-ground plant.
My 50g linked below was a dry-start done entirely with crypts, anubias, and ferns. No carpet plants. The ferns were kinda meh for the DSM, as they didn't root very well. The anubias rooted like champs, and are growing like any other plant in substrate.
