hey Chappy! your list looks pretty good, only a few notes :
IF you choose scarlet badis (and possibly the killis!) then you may have to feed them specially, as they are a micro predator, and will compete with the rasboras or danios.
ALSO, micro sword will grow taller than the marsilea, you may want to either reverse those plants, or swap one with something like Ranunculus inundatus. oh, and maybe a ludwigia as another background plant?
good luck, and happy scaping!
