Those are big fish. I wouldn't choose those personally, but if that's what you like, go for it.
If I had a 200 gallon, I'd get some angelfish, a school of boesemani rainbowfish, a swordtail, some mollies, a gourami or two, and a blue lobster (the smaller peaceful kind). But, I like lots of color, medium sized fish, and a peaceful aquarium.
You seem to want fish that will eat feeder fish. So, that is outside my realm of interest and expertise. I knew someone who had piranhas though. She liked them. She only had piranhas.
I suggest picking you're favorite fish, and building around that. That affects which fish can be kept with it based on compatibility and water conditions.
