I dont think you will know until you try. I have had cats for over 20 years and each one I have is different. I have introduced older cats, younger cats, kittens to one another and each time have had a different result.
Currently I have 3 cats. 2 are litter brother and sister, I got another kitten and the female cat has taken to him and the brother now insists on living outside! He comes in hissing and spitting, eats his food then goes again.
Its a lottery.
