Jedward are set to be asked to come save the X Factor musical – which has been axed after just six weeks.
Producers are also planning to try and get Mary Byrne and Wagner for a touring version of the West End show.
Bosses decided to pull I Can’t Sing because of extremely poor ticket sales – losing them up to €10 million.

But David King – the show’s producer – now hopes that Simon Cowell will agree to his new plan to change the show.
He said: “It was a major mistake not to include [Jedward and Mary Byrne]. That would have guaranteed bums on seats.
“People like that combined with a musical about Simon Cowell would have worked really well.”
Previously Jedward have starred in their own Christmas panto in Dublin’s Olympia Theatre.
