The legendary `Wish You Were Here` rockers last performed as a group at the Live 8 concert in London in 2005 and drummer Nick Mason is keen to do more philanthropic gigs with his remaining bandmates David Gilmour and Roger Waters.
He said the group could do "something that`s not necessarily for us, but do something for the right reasons and enjoy doing it."
He added: "I think all of us would like the idea of repeating the Live 8 concept. That`s what I`d like, and I think the others might well see eye to eye."
Nick admitted the group doesn`t need to perform for the money and said he would love to donate any money earned to charity.
He explained: "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.
"In a way the best thing would be to do a number of shows and have some sort of foundation.
"We all individually have pet projects and what we did at Earls Court in 1994 was we pooled the money and each of us decided which particular things they would like some of the money to go towards, which was brilliant. That`s the way to do it."
After bass player and singer Roger left PinkFloyd in 1985, the group continued without him until going their separate ways in 1994. Keyboardist Richard Wright, died in 2008.
