By the time you are buying second lenses for focal lengths you've already shot with, this may be possible, but I wouldn't be surprised (and you should NOT feel dissatisfied) to find even then, there are little differences which may catch you out; extra weight (if faster lens), controls working in opposite directions to what you're used to (if buying non-Nikon), etc. That said, it is a good aim to have.
