♥AQxxxxxx, ♣AQ10x any singleton, you could easily have a slam on opposite not much, you're not expecting 2♥ to end the auction, you can bid 4N over 4♠ if it's bid over your 4♥ just in case partner has a stiff heart and a lot of clubs (you've shown 7-8/4 IMO bidding like this so partner should make the right decision). If S bids 4♠ and partner doubles, at least you have some defence which 4♥ initially wouldn't show.
