Depends. I'm sure the dog will have the smarts for it but alot depends on the dog. If it has the desire for birds, which you can train them for, and (a big AND) has the ability to range then you can train it as a flusher. To train it as a pointer will probably give you fits. Either way, you are going to have a long road ahead of you. Alot of training materials already assumes the dog has certain natural traits like bird drive, range, stamina, etc. So, much is gonna be fairly useless since your gonna have instill/reinforce these traits.
