I would have the results announced at the start of the results programme, then have the bottom 2 sing straight away again.
Then for the duration of the show, re-open those 2 acts phone lines and then the one with the least votes goes.

Take it all away from the Judges full stop. After all they not only judge the acts,they mentor them and therefore have a bias towards their own acts which generally makes 2 votes from the Judges a farce anyway and waste of time each week.
