Sounds like you'll have a beautiful place and a very smallie friendly environment. However....
If SMB are your main focus, I wouldn't add a spawning population of LMB in a 1 acre pond-they just won't be able to compete with the LMB in a pond that size, IMHO.
If you really want LMB-add a modest number of adult female LMB, which will let you control numbers and prevent reproduction.
It's not just a matter of restocking the SMB. If you have reproducing LMB, the offspring each year will consume a tremendous amount of your YOY forage that then won't be available for the smallies.
