Keeping things for discussion sake, I like canyon creek's thoughts but also see you have a plan you've thought about in depth.

My pitch would be to wait on the LMB introductions into the pond. In NW Ohio, you'll be able to get healthy advanced sized LMB any time in the future whether it be from a hatchery or privately sourced. As such, I would want the SMB to get as big as possible, as the almost unavoidable takeover of LMB when both LMB and SMB coexist, and maybe sans aggressive management against the same, is bound to happen years down the line. You may find enough enjoyment without the LMB, and I don't think you mentioned Hybrid Striped Bass/HSB which would fit in nicely.

Whatever fish you end up with predator wise, they're going to have a lot to eat with your forage plan.
