Khan is preparing to defend his WBA light-welterweight title against mandatory challenger Dmitriy Salita in Newcastle next Saturday.
And the 22-year-old admitted he would love to fight 31-year-old former world light-welterweight champion Hatton.
"It is not nonsense," Khan told BBC Radio 5 Live's Sportsweek programme.
"It is a fight that could happen because we are both at the same weights, I am a world champion now, Ricky has come back into the game again from retirement and he wants another shot at a world title.
"Let's just see how things go - it is all up to the promotion side of it."
Khan added: "It would be a big British fight, a fight that the British fans want to see.
"It is just a shame we are at the same weight because we are good friends. But business is business and sometimes you have to fight your friends."
Khan has been training alongside Manny Pacquiao, the man who defeated Hatton inside two rounds earlier this year, in preparation for his first defence.
Undefeated Ukrainian-born Salita will hope to repeat the success of Breidis Prescott against Khan in September last year.
However, Khan insists that defeat has sharpened his focus and improved him.
"It has made me a better fighter," said Khan. "The way I came back from that defeat, not many could come back from it and it has changed me from a boy to a man.
"Also it has probably changed my life around inside and outside the boxing ring. I take the sport more seriously and I am totally dedicated in the sport now.
"I can't wait to fight, and show the public, and show my fans how much I have learned in the last 12 months.
"I want to keep hold of this world title as long as I can, defend it a lot of times and win more world titles on top of it."
Khan believes he has the measure of Salita.
"He has got sticky feet, slow feet and has very little lateral movement, so that will work to my advantage," Khan added.
