Rudder for final runway alignment (?)

Is it cheating/advisable/forbidden/useless to use the rudder alone to
accomplish the very last seconds of runway alignment on landing? As I
approach the landing point it becomes very difficult to turn in the
usual way just to improve alignment. Using rudder alone can line me
up perfectly right quick, but I don't know if that's the proper
technique, and I have to hold the rudder going in.

I know that the rudder can (and should?) be used to deal with
crosswinds, but I'm talking about landing in calm air and just being
an aircraft-width or so away from the centerline (which on narrow
runways or with large aircraft might mean one set of wheels on the
grass). As I get closer I'm afraid to roll the aircraft because a
wing might fall too low, or ground effect might do something
unpleasant, or something like that.
