2:10 PM PT -- Travis Kelce got wind of Mark Cuban's plea to Taylor Swift ... and fired back at the Mavs owner with a playful post on X.

"Just sign me to a ten day [contract!] 😎"

Mark Cuban has seen what Taylor Swift's relationship with Travis Kelce has done for the NFL, and he's hoping her influence can transition over to the NBA ... telling TMZ Sports he wants to hook her up with a Mavericks player!!

T. Swift's appearance at the Chiefs game on Sunday had a massive positive impact on Kansas City and the league as a whole ... resulting in massive television ratings and Kelce jersey sales.

The billionaire businessman and Mavs owner is now giving his two cents on the Swift/Kelce sitch ... and he tells us he's not only witnessing a budding romance -- he's also seeing dollar signs.

"Taylor Swift impacts the economy," the Shark Tank star said out in NYC on Thursday. "She adds value everywhere she goes."

"Literally every city she brings her tours to, you can see the economy get a bump out of it. The NFL's gotta be loving this."

Cuban sends a personal message to Swift ... saying he'd love to introduce her to a hooper so the Association can get in on the big biz, too -- that is if things with the Chiefs tight end fall flat.

"The Mavs -- we got a lot of really good-looking, young single guys. Come on!"
