"I'd do that, I would do that," he said. "She's still a little bit hesitant. I'm working though, I'm working."
"You know she's been married, I've been married. She's said, 'We have a good thing.' But I said, 'You said that 30 years ago, shouldn't there be a sea change?' Maybe there is, you never know."
Farrah, now bed-ridden and bald, has battled anal cancer for two and a half years and is nearing the final stages of her struggle against the crippling disease that has spread to her liver -- a fight that is documented in a video diary that will air tonight on NBC.
"I want to stay alive. So I say to God, because it is, after all in his hands, 'It is seriously time for a miracle,'" Farrah tells the camera in the video diary.
"Of all the things I've ever hoped for in my life, finding a doctor to surgically remove my anal cancer did not even make the top one million on my list," she said.
O'Neal said he will wake the 62-year-old actress from a drug-induced slumber so they pair can watch the heartbreaking documentary that shows her painful struggle chronicled in doctors visits and hospitalizations together, the New York Daily News reported.
In the intimate documentary, Farrah reveals her bald head, openly breaks down during doctors visits and shares a letter she drafted to Redmond, her son with O'Neal.
"For Redmond, my boy, I will always be there. When you are so very young, I will be there. When you fall, I will be there," she wept on camera. "When on day, you wake up and realize that I am gone, I will still be there, always. Always with you, forever in you, Redmond, my boy."
In one scene, Redmond, jailed for a probation violation, appears at his mother's bedside, climbing into the bed and sobbing as he tries to hide his leg shackles.
Redmond promised his mother that he would never touch drugs again during his three-hour, court-sanctioned visit last month.
Farrah's doctor told the "Today" show this morning that she's "doing well" but is losing her strength.
"She's weak and she's spending a lot of time in bed and resting," he said.
The video diary has also stirred controversy. The producer of the show filed suit Wednesday against O'Neal seeking creative control over the documentary, which he said he was cut out of the project and threatened by O'Neal.
The producer, Craig Nevius, claims in a suit filed Wednesday that O'Neal asked him to relinquish control of the company producing "Farrah's Story" and when Nevius declined "O'Neal physically threatened him," TMZ reported.
