I would still quarantine, even if not for health issues. Allow that 45 days for the two to get to "know" each other and hopefully become comfortable hearing each other.
Sunni is my Yellow Nape of 29yrs. She has her own bedroom, it's 12x14, she has a large macaw cage with a play top as well as a playstand. My computer is in her room on a corner desk. There is also a playstand in the front room.
We brought in a 1yr 3 month old CAG into our household last January in hopes of a "friend" for Sunni. Having adopted him from a friend who father is a veterinarian, she as well had blood work, fecal, DNA test (male) done. Rowdy or Peep as he is now known, was kept in the dining room for 3 months. They started contact calling each other after a bit. After about six weeks, (I know it's hard to wait- but really if you are trying to establish a bond that hopefully will last YOUR lifetime, it's worth the wait) I took Sunni out to the front room for her first eyes on him. I made no big deal of it. I just took her as we had normally done to hang out on the couch with me for a bit. We didn't even go into or stop by and look at him. Believe me, they checked each other out. I acted like it was no big deal. So did they. Peep was in his cage when I was out and about with Sunni.
So every other day, Sunni made the couch trip and about at 8 weeks, we strolled through the dining room to the kitchen. I gave her a treasured snack back in her room and then brought Peep into her room for the first time. I just sat at my computer desk and held and talked with him, no holding him up or anything. After that I alternated bringing him in and her out.
Sunni has never been clipped, she has never really offered to fly although her room is certainly big enough. Well, she will fly down off something. Peep is an excellent flyer and I had no intention of clipping his feathers. We were very careful of turning off a ceiling fans when he lived in the dining room and was out as he would fly through the house.
At the end of month 3 with my heart pounding, we put together Peep's new macaw cage (just like Sunni's just a different color). I am extraordinarily lucky with this CAG... he immediately takes to new toys and things, he flew over and got on the new cage as Phil was putting it together. We almost forgot the cage had to be finished inside the room as it's too big to go through the door

Phil finished the cage in the bird room while Sunni was out and I held Peep as he watched Phil and Sunni. When the cage was complete and set up, I let Peep fly over to it. I sat and read, facing the birds instead of my back to them on the computer. There really ignored each other.
I was afraid of letting one out and leaving the other locked up. I know someone whose bird lost two toes that way. He flew over to the other birds cage and landed and the bird ended up biting two toes that had to be amputated.
So here we are, 1yr6mo after he joined our household. When my husband comes home in the afternoon, he opens both cages. They have shown after carefully allowing them more and more freedom together, that they are capable of being out together. Peep frequently will fly over to Sunni's cage, she ignores him unless he comes within say 2 feet of her then she will open her beak and spread her wings and he will say "Back Off, Back Off!!" and fly back over to his cage

Why does he say that - why of course over the learning year when he came to close I would say it, so now he does. They each have their own playstand, Peep seems to prefer Sunni's (they are different) and she doesn't Seem to mind sharing. I came Into the room one evening and didn't see her, looked around and she had apparently got down on the floor, went over to his, crawled up and was sitting on the highest part on the play top. He was on his door, looking up at her... like "Get off, Get off"

boys.
What your hopes are, aren't unreasonable, however; as John said, be prepared it won't happen. Just don't try to rush it. Because that won't work.
One other thing, I truly believe in hierarchy with my dogs as well as my birds. Sunni gets fed first, held first, her alone in the front room with me first, her bath first, etc. He gets just as much attention, he just gets it second. The one thing he does enjoy all to him self - my husband, he absolutely adores Phil, really prefers him over me. Phil only tolerates them and does hold him someones as Peep will fly through the house looking for him when he escapes the bird room. Sunni? She hates the breath he takes
Good luck and keep us posted
