Vieja can be very aggressive, I wouldn't do a large vieja with Acara's, heckelli and rainbows. If you wanted to do the vieja, I would up the aggression of your small cichlid choices a little bit. Sajica would still be fine, for the others I would look to thoricthys and cryptoheros/salvini, nicaraguense, things like that. Pearsei are another large choice which are less aggressive than Viejas. And I still think you'd be better off avoiding two males of the same species (sajica)
EDIT- didn't see your latest post. That stock list looks fine, And Heckelli would be a good choice
