I'm not sure I entirely understand your question. But if you mean simply moving all of the fish into your one large tank with some being smaller then the answer is it could or could not work.
Hard to say things like this without sounding negative, but these fish were not meant to be kept this way. The "one of each" type tanks are unpredictable. You will have an odd mix of territorial fish. So honestly, nobody really knows if it will work or not. The large fish may bully and out compete the smaller fish, preventing them from looking their best. Or the large fish could simply kill the smaller one day. Not to mention, everybody's definition of what works is different. I have seen some threads on here where people post their tanks, say the fish get along, but there is obvious damage to fins on some fish. Personally, I would not like that in a show tank, but in their opinion it works.
So that was a longer way of saying, it could work!
