I've raised lots of cichlids but not the rams. Buy in general I find there are some rules to follow when you are not sure.
How big is the interest balanced against things going bad over time? If you really want them and you do have a nice tank for them, it may get down to how you feel if it should become necessary to move one or more out of the tank. I find that if the fish are not grossly overcrowded or one fish is not terribly undersized, any problems that come up will not be sudden and a disaster. You will normally have plenty of time to see trouble starting if you are a bit watchful. Same size fish rarely kill each other without warning when speaking of cichlids. There should be many signs of a gradually increasing problem.
That brings it back down to your personal outlook. I often try things that may not work full time and long term. It gives me a much broader range of things to do with my fish if I don't worry about moving or trading somebody.
If it tears you up to trade any problems, don't try it. But then if you feel a bit bolder and really want them, It may work fine.
Just watch them and have a plan in the back pocket so that when you spot any real trouble brewing, you will be able to act before the week is up.
