The 'Light My Fire' band's original guitarist Robby Krieger and drummer John Densmore are planning to stage a concert for the keyboardist, who passed away in May after a long battle with bile duct cancer.
Robby told Rolling Stone magazine: ''We're going to do at least one show for Ray and have a big send-off. That's either the start or the end of it, I don't know.''
The fourth founding member of the band, singer Jim Morrison, died in 1971.
The concert will mark the healing of a rift between the two musicians, which started in 2002 when Robby and Ray started touring as The Doors of the 21st Century. This led to lawsuits from both sides for millions of dollars about the rights to use the band's name and songs in adverts, and a book by John, 'The Doors Unhinged' about their battle, although Robby claims this is now behind them.
He said: ''[John's] the one that got me in the Doors. What am I going to do? I can't hate him forever. I just wish he had wanted to play with Ray and I back before all this started. That's when things went bad. We're talking about it.''
Robby also didn't realise Ray was as ill as he was, and had hoped they would play shows booked for August.
He said: ''I kind of noticed on the last tour that he was slowing down a little bit. He had a good run. For a rock & roller [74 is] a pretty good age.''
He also told how the pair had worked on new, as-yet-unreleased, material together in 2011.
He explained: ''We never finished it. We worked on some stuff with Ian Astbury. Maybe something will come of that at some point. It was some pretty good stuff, actually. We couldn't call it the Doors. We didn't know what to call it, and we kind of gave up on it.''
