I've just came up with an idea (sorry golf addicts
) If a player changes cues midway into the rack, he(she) continues playing with this very cue until the end of his(her) inning!
Imagine running out with a shorty, LOL
A player must make a shot, i.e. drive the cue ball with the stroking motion of his cue. Trying to pass turn in a manner you described is unsportsmanlike conduct, under official rules of play.
Hence, even in such a situation a player is expected to make a move, as if playing chess. Change the position of the balls, even slightly. In case both players don't wish to disturb the position due to risk of losing the rack, three turns at the table with no obvious proceeding to the end of the rack results in a stalemate. Again, see world rules for this one.
