I think you could get away with the Rams and Kribs in the 40 breeder....heavily planted especially. I have never kept them together, but I have kept several pairs of Apistos successfully in a 40br...different species, so they didn't all get along all the time.
I wouldn't put Angelfish in the 14g. Yes, its a tall tank, but its only 14g and I'm not a fan of putting them in anything less than 40 gallons...unless its a single one and then no less than a 29g. That's just me though.

I would do like an interesting school of fish and since there isn't a ton of room in a hex tank, I'd just have 1 school and then have some type of centerpiece fish like a small Gourami. Honey Gouramis are nice and small....and peaceful, for Gouramis. Killifish are cool if you can find them. A pair would go nicely with some type of school....just have to keep the tank covered because they jump.
