Travis Kelce would be awwwweeeeesoooome in the squared-circle ... so says WWE Superstar The Miz, who tells TMZ Sports he'd love to see the Kansas City Chiefs superstar -- AND his brother, Jason -- take their talents to wrestling!!

Remember, we spoke with Travis back in April about possibly seeing him follow fellow tight end greats like Rob Gronkowski and George Kittle by getting into wrasslin' ... and he said he's already talked to Miz about making it happen.

Naturally, we had to ask Mike all about it when we caught up with him at LAX this week ... and while it doesn't sound like anything concrete just yet, it's clear he's put a lot of thought into it.

Miz -- who admitted he's blown up Travis' DMs over the subject -- said it would be perfect to see the Kelce bros team up for a special appearance at WrestleMania ... especially considering it'll be in Philadelphia, a city Jason is VERY familiar with.

Of course, Miz knows firsthand what it's like to go up against NFL stars -- he took on both Kittle and Pat McAfee at the same time at SoFi Stadium earlier this year.

Miz also feels like WWE could see a similar boost as Roger Goodell's org. if it happens ... thanks to the Taylor Swift effect.
