Removal of BG outside the gape size of the larger SMB is a very good size to be removing in addition to the female BG. Personally I would remove BG that are 70%-80% (1.5"-1.8" body depth)of the maximum gape of your SMB. I doubt very much that SMB are eating gape size BG very often when smaller forage or pellets are available. FYI my measurements indicate gape of a 17" SMB is very close to 50mm (1.9")vertical and 58mm (2.25") horizontal. A BG at 5.2"-5.5" has a body depth of 50mm.
I think one adult female BG (8") can provide all the YOY BG your pond will need for your goals. Plus you are going to have RBS, PS, and YP small fish.
