Well, this isn't exactly what you are asking but perhaps good enough.
I had a 90g with a mated pair of false percs and a single gold stripe maroon. The female false perc immediately established dominance as I added the maroon much later (since it was the most aggressive species I added). Within a few days they had established territories on opposite sides of the tank and neither went into the others territory. If they did, the other would charge but stop in the no-man's-land in the middle. I had both species for a long time and never had any problems. Don't take my experiences to mean it's a guarantee though. However, my opinion is that you won't have any problems with two pairs of the species you mention.
