Interesting thread. In a couple of months, once my university studies let up (!!for a while, dag-nabbit!!) I'll be asking ya to pass the dutchie on the left hand side, if you know what I mean. In the meantime...

Without Waters "grubby fingers" there would be no Floyd. He was, in fact, a founding member. Gilmour was with them from the start as well, he simply didn't appear on Piper. Barrett remains a headcase.
As for the current Floyd, or any since (what was it, 1983 for the Final Cut)...
a Floyd without either Waters or Gilmour is like the Beatles without either Lennon or McCartney.
I know I've been mad. I've always been mad, like most of us are. It is very hard to explain why you are mad, as to explain why you are not mad.
