Will we see them again.....?

[Con]

Yes.

1. Rock Bottom - Booker T's Book End Move
2. Stonecold Stunner - Mr. McMahon and Eugene used it before.
3. Lionsault - Chris Jericho may return.
4. Piledriver - Kane and Undertake use this.
5. Angle Slam - No one else uses this yet.

Any move can be used by more than one superstar.

Your theory of 'A new wrestle cannot use such moves as they are legendary.' is not well thought out. Many wrestlers use other wrestler's as a tribute. For example, Chris Benoit uses Eddie's 'Three Amigos' move in tribute to him.
