My short answer would be yes you can, but it takes some careful planning and a decent amount of "work" to make it happen. And you will need to keep up with monitoring the pond down the road or it will slip right back out of balance. Would be helpful to hear your goals so people could give better advice. In a pond that size, my non-expert opinion is that large BG/Crappie and also large LMB will be almost impossible(or very expensive) to attain and sustain because they are counter to each other.
