Weitz, whose new film A Better Life opens in the UK this Friday, confessed that he doesn't want the Twilight trio to feel like he is using their fame to get his future movie projects made.
He told Digital Spy: "I hope they know it almost goes without saying that I would like to work with them again because we had a great time with each other.
"We haven't really brought up individual projects yet, it's really a question of what would fit perfectly. That's hard to find.
"I would never want any of them to think that I was trying to trade upon their celebrity to get something made. It would have to be something very specific, what each of us could do."
Weitz's Twilight instalment is still the most successful movie adaptation of Stephenie Meyer's vampire novels, taking in more than $700 million (£435 million) at the worldwide box office.
