You *could* make a custom alias for it...

Code:
alias kban {
  if ($1 ischan) {
    var %cnt = 2
    while (%cnt <= $0) {
      var %bans = %bans $iif($($+($,%cnt),2) ison $chan,$address($($+($,%cnt),2),2))
      inc %cnt
    }
    ban $1 %bans
    kick $1 $2-
  }
}


Use: /kban #chan nick nick nick nick

As a note, you could also have the ban type specified:
Code:
alias kban {
  if ($1 ischan) {
    var %cnt = 3
    while (%cnt <= $0) {
      var %bans = %bans $iif($($+($,%cnt),$2) ison $chan,$address($($+($,%cnt),2),$2))
      inc %cnt
    }
    ban $1 %bans
    kick $1 $3-
  }
}


Use: /kban # <type> nick nick nick nick
Example: /kban #chan 2 nick nick nick nick
