What if your favorite singing shows had an epic crossover event? It could happen if Simon Cowell gets his way.

Cowell threw down the gauntlet last week, proposing a “Super Final” challenge, which would pit the champions of TV’s top singing competitions against each other for one ultimate winner. A face-off between “American Idol,” “The X Factor” and “The Voice“? Now that would be one serious Battle Round.

And at least one former champ is up for the challenge.

“The Voice’s” Season 1 winner Javier Colon, mentored by “Voice” coach Adam Levine, responded Monday to Cowell’s proposal.

“So @simoncowell recently proposed a face off btw Idol/Xfactor/Voice winners,” Colon wrote on Twitter. “I respect the other winners a lot but if U want a battle I’m IN!”

“Just letting U know that I’m down! #itsonyousir” Colon added, throwing the ball back in Cowell’s court.

“Idol” executive producer Nigel Lythgoe also piped up about his former judge’s idea: “@simoncowell suggests the IDOL winner should take on the voice and x-factor winners,” Lythgoe tweeted. “The problem is the Idol winner will be a star by then.”

Something tells me a “Super Final” challenge still wouldn’t settle the battle between these guys’ egos…
