Scott I agree with others that you can do what you described . The biggest mgt. matter will be controlling BG #s population. That can be done as provided in the posts above. The last 2 PB issues have discussed the option of not using BG in a northern pond but instead using the combo of FH , GShiners and SMB . If you use that combo and add RES and YP and some craws you may have a great mix. Any thoughts or comments?
