To answer about the teeth, at 8 months old most of the time the will not fix but sometimes if it just the front teeth and the canine still have correct alignment the bite will fix. Sometimes the teeth in the front will change alignment several times. They may or may not produce it in their immediate offspring but even if their offspring have good bites, the issue can crop up again in a future generation.
Since you are having the issue of her not getting along with another dog, it probably isn't going to be worth waiting and hoping that it fixes and then possibly having it go off again at later age. If you really think she may be an asset to your breeding program other than her bite, maybe you can find a co-ownership arrangement where the new owner will not be too disappointed if her bite never fixes and she is really just a well loved pet.
