First of all, don't use acid and alkaline buffers, they do nothing useful but can do harm. Second, you have a very, very strange wish - instead of controlling 100% of your water quality, you want to go 75% in (so, invest pretty much the same amount of effort) and still leave 25% to pure dumb luck? This really doesn't make much sense... Third, one is remineralizing the water to reach a particular desired water composition, so without knowing what are you actually trying to achieve (what KH/GH) and what are the parameters of your tap water it is impossible to answer your question.
