Capture all Black's main pieces in 15 moves.

I found this unusual line where White wants to clear the back rank to promote the f-pawn in 7 moves. Is this a bad puzzle? If you think it is, I'll remove it.

looks cool

I feel very uneasy about it. I like the idea of simplifying the position on the back rank to promote a pawn. But, is the White Queen sac realistic? Can that be calculated with any degree of confidence? Can Black disrupt the exchange sequence somehow so it doesn't lose the exchange?
