Alas, american cichlids don't like to be crowded, instead of spreading the agression out like rift lake cichlids, they all pick on the weakest until it's dead, then the next and so on down the line.
Your idea of 4 single smaller species should work, but I would skip the keyhole. Despite getting 5", they act like a dwarf cichlid and are very timid usually. Most specimens would be terrorized by a convict and firemouth.
The blue acara should be able to hold it's own, as would a port cichlid or even a west aftrican jewel cichlid.
