I had a jardine and, although I never have had a crimson bellied, I've had and still have a GCC which are very similar in size and temperament and I really do not think you will have a problem. Granted, I only had one jardine and having one bird of a species doesn't really give a whole lot of insight into the species, it just teaches you about that individual bird, but, for what I have read about them, in general, and from other owners, mine seemed to have been pretty 'standard' when it came to personality and she is the sweetest, sweetest thing! She also got along just fine with all the other birds in the birdroom - never, ever, ever gave a single problem about that and I had her for ten years and she shared the birdroom (they live cage-free) with lots of other species, from budgies to macaws. Crimson-bellies are, apparently, very similar to GCCs and mine is bonded to a bird of a different species and it happened fast and without a single hitch (it was entirely their choice, not mine) and going by the many other inter-species bonding examples, I would say that it's not rare at all for this to happen.
Will they get along when they become sexually mature? Nobody can answer that question for sure. One cannot even say that the bird will even like its owner once it matures as there have been many examples of birds that turned completely against their owners when they went through puberty. But, for what people say and going by my limited experience (I don't take in young birds, usually, so I've only had about three of four juveniles), it happens much more often than not to the point that, when people want two birds to bond, it's usually recommended that they are acquire both when young. It's the older birds that are used to been by themselves that usually have a problem. Sharing and cohabiting with their close and extended family is, after all, what they do in the wild so it's not as if one was expecting them to adapt to an unnatural situation, quite the contrary! The unnatural situation is for a parrot to grow up and live alone.
Now, I would not worry about them vying for the top bird position because this is based on the concept of a hierarchical society and we know now that parrots flocks are not structured that way. There could be jealousy but all you would have to do is to offer the same amount and level of attention to both and they will do just fine. If one can take two separate birds that lived alone separately with a human for years and get them used to sharing a third human, I would say that doing it from the beginning would be much, much easier.
Of the birds I currently care for, my GCC came to me during puberty (she was about a year and a half old) and my jenday had not gone through it yet (he was nine months old) and they both do GREAT with other birds! No jealousy and no aggression whatsoever.
Personally, I think that all parrots should have a companion of their own. So much so that I actively look for suitable companions for the 'lone' ones and put a lot of time and work into getting them to bond. I was never able to get another jardine for mine to bond to and that was the main reason why I returned her to her original owner recently (the lady is now retired and living alone so she can spend all day long with her). She did hang out with the timneh gray and got along with everybirdy but she never had a companion of her own and that was something that bothered me terribly so, if I were in your shoes, I would not doubt for one second and get them both (and I would jump for joy in the process!). But that doesn't mean that you cannot provide a single jardine a good home, either! So, that's my two cents.
