Who could have been in Pink Floyd and had made a great job in the band?

Who you think that would fit nicely in Pink Floyd, or could have done a great job in the band, or has the style so alike as one of the members that would be the same if he was in the Pink Floyd, etc...???? (for example you could name a bass player that would fill roger's empty space left after he walked away, or a pianoman with same sound and technique as rick, i dont know you just say what you think)

I always thought Robert Fripp from King Crimson. Or Rick Wakeman from Yes on keyboards.

Mr Harris, my old history teacher, would have been perfect to stand in for Roger. He was right twat.

Shakin' Stevens would have made a novel addition to the band!

jeff beck on gtr!

- the virtuoso player was offered the job when barrett began his descent into madness but he turned the band down

Instead of all the band members: cardboard cut-outs and playback tapes.
