I guess I tend to think of them both as top fish and I've seen swords harass guppies. I also expect the angels to hog the mid/top of half the tank, so the rest of the fish will have a smaller area. I also your think stock list is a little heavy, esp. if the livebearers start reproducing (though I'm sure the angels will eat fry, and the livebearers will eat angel eggs). Its just my opinion, and its not fair of me to judge since I don't know your filtration or water change schedule. Still, I'd rather see you go up to 8 (1m to 3f) of one kind or the other. You don't have to start with all the fish, you can add more later. Although, if you add the tetras later, the angel could decide they are live food. I think cories are a good ideas, but you need 6-8. They will love the sand.

I like your plant plan. There are plants that do best tied to rocks, I just don't know which ones.
