Here's why it's unlikely:
* Quidditch is serious: Quidditch is a very important sport at Hogwarts, and the players are generally focused on winning. Dressing up in a silly costume would be distracting and disrespectful to the game.
* House pride: Students take their House pride very seriously. Draco wouldn't do anything that would make Slytherin look bad.
* Draco's personality: Draco is typically arrogant and self-centered. A silly costume would be out of character and he wouldn't want to risk appearing foolish in front of his peers.
While we don't know if he's ever dressed up for a Quidditch match, we do know he's quite the dedicated player and always eager to show off his skills and win for Slytherin.
