The group last played together in 2005 and Mason said he can see the group reforming to do "something that's not necessarily for us, but to do something for the right reasons, and enjoy doing it," the BBC reported.
The group broke up in the 1980s, but got back together for the Live 8 concerts in 2005, and bandmates Roger Waters and David Gilmour recently played together for the first time since Live 8, when they performed three Pink Floyd classics for the Hoping Foundation, which helps Palestinian children.
"I think all of us would like the idea of repeating the Live 8 concept," Mason said, speaking at the In The City music conference in Manchester.
After the Hoping Foundation performance, Waters wrote the performance was: "Great. End of story. Or possibly beginning."
Gilmour will also be a surprise guest during one date on Waters' upcoming tour, where Waters is playing the band's album "The Wall" in full, the BBC noted.
"I think it would be a very nice way for a band to gently move towards retirement, by doing shows absolutely for charity rather than for more income," Mason said.
