Welcome to PB!

I have a very similar pond in central Missouri. I added HSB but don't have WE.
Based on my experience over the past four years I believe your plan is generally sound, but recommend you carefully consider removing BG/HBG from the mix.

SMB are not able to keep BG in check. I soak traps 24/7 from March until November and pull out every BG I catch that's <9".
BG are also are savage little nippers who will plague swimmers mercilessly, so if you plan on using your pond as a swimming hole you don't want them.
