The camp dance act, who are competing in this week's live BGT semi-finals, asserted that they could do better than two-time entrants Jedward and the 2012 UK representative Engelbert Humperdinck.
"There have been rumours that we could be on the next Eurovision," the group told Digital Spy. "If Jedward can do it dear, we can do it. [And] there's not a sequin in sight on [Humperdinck]. But we have had slightly more work done between us.
"Red, white and blue sequins all the way. Spread the sparkle, that's our motto. We need a bit of glamour in it, dear. It's nice to be thought of this early because what [we're] thinking is rather than vote on the best song this year, we should vote for where we most want to go on holiday next year."
Despite saying that they have "no delusions" about winning Britain's Got Talent, The Showbears revealed that they have already thought about the Royal Variety Performance and would like the judges to join them.
Asked if David Walliams had been invited to perform with them again in the semis, they explained: "It would be a bit too obvious if that happened. I think if they got on this time [we'd] just shove them straight off stage and say, 'Get off this is my moment. You've got Britain's Got More Talent'. We could get Simon Cowell a pair of gold sequin high waisters just in case.
"If we do get the opportunity to perform at the Royal Variety we can get all the judges on then. And the Queen. She can come down and join us if she likes."
The Showbears previously announced to Digital Spy that future routines could be themed around Harry Potter, Fame and the Royal Family.
The first Britain's Got Talent live show will air tonight (May 6) at 8pm on ITV1.
