Very doable, Wackie. I'm only speaking from personal experience; that experience is limited. Here's a study that was published in PB:
http://www.bassresource.com/fish_biology/pike.htmlThe study found that northern pike consistently have a detrimental effect on the size structure of yellow perch, as the pike crop the perch population from the top down. However, average largemouth bass size increased significantly in every BOW in which pike were introduced, including three ponds and a 60-acre lake. The bluegill population suffered in the large lake, probably because as the study notes the pike spawned successfully and became numerous in the lake; in the three ponds pike were stocked in, as the bass size increased, "quality of bluegill populations remained high."
There were no ponds in the study above that began with overpopulated sunfish. Here's another article from PB that recommends pike for ponds in which bass are crowded and the pond owner wishes to thin them to produce bigger bass, while maintaining good bluegill size:
http://www.bassresource.com/fish_biology/walleye-bass-perch.htmlIt's possible my results were a fluke. But I do have firsthand experience in thinning a stunted population of sunfish with northern pike, and my personal experience was that they worked better than I ever dreamed they would, with the nice bonus of making the pond into a trophy-bass fishery at the same time. Just my experience.
This hatchery sells northern pike:
