I don't know if you did a lot of research on Syno's but they are known to be egg and fry eaters. They eat at night so I don't think you will have much breeding issues. As a matter of fact people keep synos with fish they are worried about hybridization with. They know the eggs will never have a chance to hatch because the synos are in the tank.
Pulcher's are supposed to be highly aggressive so they probably will be very territorial.
I know you like blue but what about Leleupi they are a pretty orange. I am trying to think of blue but most of the popular fish from that lake like calvus and comps are yellow and black and stuff.
A lot of the feather fins have pretty blues in them but they take up a lot of floor pace because they build big sand bowls to attract females to spawn. You couldn't do very many maybe a trio. That way you will get the two males to display colors to try to attract the female away from the other male.
