Aldo will fight Pettis on Aug. 3, with venues in Brazil, Las Vegas, Chicago and Texas the leading contenders to host the event.
"I want to fight for a belt, man," Pettis said. "That's the intriguing part for me. It's another belt, and I don't think the weight cut would be impossible. I think it's something I could pretty easily do."
Pettis is coming off back-to-back knockout wins over Donald Cerrone and Joe Lauzon. As for Aldo, he eked out a close decision victory over Frankie Edgar at UFC 156.
"I only cut like two pounds to make 155," Pettis said. "I have a clean diet and I barely cut any weight when it's time to get down to '55. I mean, if my teammate Erik Koch can do it, I'm pretty sure I could."
To fight Aldo, Pettis would need to lose ten pounds more than his typical fighting weight.
"Right now it's so fresh and brand new, that I'm just trying to clear two paths to get to both of these belts," explained Pettis. "I mean, they say, ‘You can fight Jose Aldo in three months, and then you get the winner of Henderson-Gilbert,' then I'm signing the contract today.
"That's up to the UFC. I'm not going to make any decisions or close any doors until they decide what they want to see. I put my opinion out there, I'm up for either one, and I guess it's just what would make sense for you guys now."
