Why not use the $snicks identifier:
Code:
alias kotunick {
  msg $chan $snicks $+ , your nick is bad. Please change it in 60 secs or you will be kicked and banned.
  .timerkick 1 60 kicksnicks
  .timerban 1 60 bansnicks
}
alias -l kicksnicks { 
  tokenize 44 $snicks
  mode # +b $* $+ !*@*
}
alias -l bansnicks {
  tokenize 44 $snicks
  kick # $* Your nick is bad, please change it.
}

Just highlight the nicks you want to kick and ban.
