Maui encroaching

It has been nearly a week since Manzi and Maui are perching together. It is funny. Maui now is nearly at the halfway point on the perch while Manzi is at the very edge. Maui starts at the edge, but slowly gets closer and closer to Manzi. He will walk over to her to harass her a bit and then run back surprised that not only does she not back down, but she seems to enjoy his attention.
Manzi still seems very perplexed. He is no longer showing much aggression, but he does still fluff up at Maui. Either way, it doesn't work.
Soon I hope to take them on the shower perch together. That perch is much smaller, but they seem to be just fine. No more jousting or anything like the first couple of times they were stuck together. They do bite beaks, but much more respectfully. At first they had lunged at each other and gotten quite worked up (as you can see in the photo below). This gives me a lot of hope for being able to cage them together. The only problem with that is that Manzi's cage would be better than Maui's cage as it is so much larger, but there is probably no way that Manzi would allow Maui to enter his cage.
Maybe I can get an even larger cage that they can both enjoy. I had thought about sectioning off part of the living area for them, but that might be too much work, be too expensive and cause too much damage to my rented apartment.
