Need some Advice

I have a question,

I have a Blue Fronted Amazon who is about 8 years old, He only has one foot, his right foot is just a stub, he got it caught in a rope toy when he was just a baby and we had to amputate his foot.

He still has balance issues, He walks around on it just fine, but he falls from his perches some times.

I have him in a small cage right now cause i am terrified to put him in a larger cage because if he falls from the top pit may kill him.

But I have an idea, I dont have room for another large cage right now, but....

I have a ferret nation cage with 2 ferrets in it, If i seperate the top from the bottom and put the ferrets on the bottom of the cage, could i put the blue front in the top part of the cage?

I clean the ferrets litter everyday, and i keep their cage extremely clean, i love ferrets but i don't like their poop or their smell, so I clean them constantly.

If they are separate and i continue my cleaning of the ferrets cage, could i put the blue front in the top part of the ferret nation?

There is a breeder that lives by me who gave me the idea, she keeps her eclectus's in a whole ferret nation,

and since my blue front, that i named lefty, can't go in a large cage, cause he falls he will hurt himself, would this be a plausible solution?

If i do this, they will not be able to touch each other, i just wanted some feedback, I don't see why this couldn't work, as long as i keep the ferrets clean and sanitize the top of the cage where the bird will go. I just wanted some opinions.

Thank you for reading this and I appreciate any responses.

Ferret Nation cages are made quite similarly to parrot cages, so in that regard they would make a fine cage for a bird. However ... Ferrets naturally prey on birds - this seems that it might cause problems. Is there anything but cage bars separating the top from the bottom? If the bird was on the bottom of his section and the ferret near the top of their section they could bite/fight through the bars - you don't want your bird loosing his other foot. But more significantly would be the stress of seeing each other at all times - no escape.

Unless the ferrets and the bird are okay with one another - ie they already interact well - I'd say there could be problems with that set up.

The cages would be on top of each other but there would be no possible way for them to see or touch each other, the two sections would be completely seperate of each other.

In that case I wouldn't see any problems.

The only other possible issue I could think of is the coating of the cage. Is it bare steel or is it coated? Some such coatings can be dangerous for birds, though I suspect that ferrets would be susceptible to many of the same things - so if the coating is safe for ferrets it probably is for birds as well.
