What birds can be kept and breed in same aviary as indian ringnecks or lovebirds?

I breed as a hobby. I would be really hesitant to put any species in with Indian ringnecks. They (mainly the hens) are super aggressive during breeding season. We have lost a couple males due to hens attacking them when the season starts. If you have an aviary setting and want different outcomes maybe you should think of one species ( like IRN's, lovies oe atiels) but do different mutations of them.
