Carlos Carvalhal's men will face whoever finishes third in the Championship.
The Owls' 3-0 win over Cardiff City guaranteed that they would finish the regular season in sixth place in the Championship and face the team that finishes third in the semi-final.
And with Burnley's weekend victory securing their automatic-promotion, Sunday's clash between Middlesbrough and Brighton will see one of the two join them in the top flight while the other will face Wednesday for a place at Wembley.
And Hooper suggested that the agony for the loser of missing out on a top two place will boost Carlos Carvalhal's side's chances of going through when he was asked about whether one side's disappointment could be used to the Owls' advantage.
"We could in a way because they're going for automatic," he told the Star.
"We're in sixth, we know we're in the play-offs already and we can prepare but anything can happen.
"But whoever it is, we have to play our own game and focus on ourselves.
"It's the play-offs, anything can happen."
While the third place side may have done better over the course of the season, it is often the team that carries momentum into the additional games that ends up coming out on top.
And with Wednesday buoyed by guaranteeing their spot in the top six, it may be they who carry the momentum needed to secure that final place in the top flight.
