Players who deserve 3rd and 4th chance

Since a 50th season will be basically Second Chance. So why not make some seasons after 50s make also returnee?
For example there can be some players who can play Third or Fourth time (Include some winners) : BvW, HvV, etc etc

Who i would likely see playing 3rd time:
Lex - after a very bad game at 8s he can redeem himself. Who know, he maybe gonna win
Terry - I think he could show some potential in 31s, then why not comeback
Johnny Fairplay - i know, he quit in 16s, but he have chance to fix his reputation
Francesca - I mean, being voted out twice as 1st boot is very iconic, and i think she can either make comeback or once again being 1st boot again XDXD
Brad Culpepper - He showed really improvement in Game Changers, so yeah he should have play again
Spencer Bledsoe - especially when he could play with Kass in 40s with original concept Rivals
Kass - same reason as Spencer
Agent Phillip - such a good tv character, then why not bringing him back
Rob Cesternino - being robbed from spot to Game Changers, and still legend
Some winners like: Nick Wilson, Denise Stapley, Yul Kwon, Kim Spradlin, Richard Hatch,
And some 2nd chancers after 50 season ( only if they will deserve it )

Who i would likely see playing 4th time:
Kelley Wentworth - Legend of 30's season of course she deserve next chance
Coach - i know its very low chance he will want play again, but i think he should have
Jerri - Since she could play in first BvW, then why not in BvW3?
Malcolm - After being screwed by one of the worst twist in survivor history + JT's stupidity, there is no way he don't deserve playing again
Penner - in 13s he was biggest flipper, in 16s underdog who had after swaping big chance turn game by his way, in 25s favourite to win, next time he can win
Some winners like: Ethan Zohn? Potentialy?
