the short answer is no, if you set up a tank to breed bristlenose or plecos in then you will just have to accept the fact that they can be a bit dull to look at compaired to a planted discus tank. Thats just the way it goes.
Any of the egg laying fish are out as the eggs will make tasty food for the bristlenose and they attack during the night when the parents are not as able to protect their eggs. Live bearers are sometimes ok but it depends on the tank. I breed in tanks that are between 60-90 ltrs and they could make nice little community tanks with several other smaller fish swimming around. the issue is that you want to be able to keep the water perfect and be able to mess around with it when triggering a spawn. Adding other fish into the water will just make these things harder.
If you had a large enough tank and the filtration was excellent then you could go for endlers, they are very attractive little fish and are easy to middleing hardness to breed.
of course the are ways to protect eggs/fry etc in community tanks and these can be applied to breeding tanks too but the more you try and diversify the tank the less likely anything will breed.
