I try and shoot lots of does and still hunt for a big buck, but then again I do so over 5-6 properties. So to me it seems quite doable. You only have one real place to hunt right? Can you just keep taking them at the fringes? I don't think it matters how many deer you educate, but moreso WHERE you educate them. If you keep zapping does in a relatively small area, and leave others as safe havens, then when the rut nears, take your stabs in there and I think you would still have a decent shot.
