Probably not gonna work out. Senegals are known to be one person birds which in other words means they only accept their mate and attack anyone and everything else. They are even known to be mate killers and will kill their mate after many years of sharing a nest together.
I know at least several people who have had major accidents by combining other parrots with a Senegal. I know someone who had a Senegal bite a Quaker Parrot's leg off through the cage bars. Someone else on this forum had a Senegal Parrot sneak out of its cage and kill their Conure in its cage when they weren't home. Lots of other chew and attack marks on other parrots from Senegals. They can be real bullies. Also, they'll go after birds bigger than their own size and put themselves at risk of counter attack by something much bigger.
Senegal Parrots can get super jealous and that leads to aggression. You can using taming, training, scheduling, and diet to moderate some of this but you can never entirely eliminate it. With a lot of effort, it is possible to teach other people how to behave around the parrot and overcome problems. Not possible with another bird because they react in their own ways. Not many birds can stand up to a Senegal Parrot and I can tell you for a fact that my Cape Parrot who is 3x bigger is terrified of her.
Since you are into clipping birds, it's even more likely to encourage fighting and endanger them. If they are kept clipped, on separate stands/cages, out of cage time supervised, etc you are probably fine but essentially they cannot be accessible to each other by foot or they will fight. From what it sounds like, yours climbs around a good bit and feels like it owns the whole house. That will definitely trigger a lot of competitive aggression. Don't even for a minute think you will ever cage another bird with that Senegal. Even in my 8x12x7ft aviary with 2 flighted parrots they just barely get by without fighting but inevitably Truman can't do anything when she's around. Anything smaller than that and there would be blood.
You said that everyone gets along well with the Senegal, why in the world add another one and disrupt the successful balance?
