THe RCS would be fine with the cories, just probably not with the bettas. I'd also go with adding another couple of cories to each group just to make them larger schools, unless they already school together. IME pygmys and habrosus's usually will school together since they look so similar.
Tetras sound like a good idea, but be weary that neons tend to be fin nippers.
If it were me, id go with something not so bright considering males ban be pretty aggressive towards colorful fish, but if you trust yours not to, i would get male guppies or some rasboras or a different variety of tetras instead.
