Ouch! This may not sound nice but feel must warn you on one bib point. Do a bit of checking on the angelfish/ neon combo as I normally do not recommend it. Do some watching as you chase some of the neon around and you are likely to find they go up to the top, then look at how the angelfish behave and you might note that they are often looking upward when food hits the water.
Neon do not have it in the genes to go down and hide and that puts them in exactly the spot where angels look for food! At some point, the angel gets big enough to do the natural thing.
Other than sounding like a wet blanket on the whole program, I do like the idea of a group of cories as they fit well with the others and rarely cause any difficulty while they are certainly entertaining to watch. I tend to think of them as the circus clowns of the tank as they bumble and stumble around, shooting to the top to catch a bubble of air and often landing smack in the middle of a group of their fellows who may shoot off as if bombed!!
