My 2 cents, Leave the HBG out. Trouble later in my mind.
I would double the RES to 400.
I'd plan 3-5" stockers and it will be full of young by fall. HSB I believe would be fine in fall of 2020.
I'm fairly sure your biggest sunfish will be from your original stockers and if you stock LMB the following year you will continue to see large sunfish, just not as many, but I believe that to be what you want. You will want to start pulling some LMB over 15" when you start to see fewer and fewer sunfish numbers of substantial size.
