what kinda rainbows and angels are you doing?
and what plants are you thinking of? I'd recommend with your lighting have even more plants that are low light tolerant, because honestly I think a planted + (I know you have two but its a single row so its better to think of the whole row of light as 1 unit) is going to be a pretty decent lighting in the area its over. Besides, there's a bunch of large low light plants that'd be nice for this kind of tank.
Only warning I have is the loaches. They are known for punching holes into swords and other plants, especially as they get bigger. Plus as they get bigger its harder to keep them with plants. I'd personally skip them for a planted tank honestly, but that's me.
