you can make this part

 on *:INPUT:#:{
  if ($1 == .op) {
    if (!$2) mode $chan +o $me
    if ($2) mode $chan +o $2
  }
  if ($1 == .deop) {
    if (!$2) mode $chan -o $me
    if ($2) mode $chan -o $2
  }
  if ($1 == .voice) {
    if (!$2) mode $chan +v $me
    if ($2) mode $chan +v $2
  }
  if ($1 == .devoice) {
    if (!$2) mode $chan -v $me
    if ($2) mode $chan -v $2
  }
  if ($1 == .aop) {
    if (!$2) services aop $chan ADD $me
    if ($2) services aop $chan ADD $2
  }
  if ($1 == .sop) {
    if (!$2) services sop $chan ADD $me
    if ($2) services sop $chan ADD $2
  }
  if ($1 == .vop) {
    if (!$2) services vop $chan ADD $me
    if ($2) services vop $chan ADD $2
  }
  if ($1 == .delaop) {
    if (!$2) services aop $chan DEL $me
    if ($2) services aop $chan DEL $2
  }
  if ($1 == .delsop) {
    if (!$2) services sop $chan DEL $me
    if ($2) services sop $chan DEL $2
  }
  if ($1 == .delvop) {
    if (!$2) services vop $chan DEL $me
    if ($2) services vop $chan DEL $2
  }
  if ($1 == .owner) {
    if (!$2)  mode $chan +q $me
    if ($2) mode $chan +q $2
  }
  if ($1 == .deowner) {
    if (!$2)  mode $chan -q $me
    if ($2) mode $chan -q $2
  }

into this

 if ($1 == .op) { mode $chan +o $iif($2,$2,$me) }
  if ($1 == .deop) { mode $chan -o $iif($2,$2,$me) }
  if ($1 == .voice) { mode $chan +v $iif($2,$2,$me) }
  if ($1 == .devoice) { mode $chan -v $iif($2,$2,$me) }
  if ($1 == .aop) { services aop $chan ADD $iif($2,$2,$me) }
  if ($1 == .sop) { services sop $chan ADD $iif($2,$2,$me) }
  if ($1 == .vop) { services vop $chan ADD $iif($2,$2,$me) }
  if ($1 == .delaop) { services aop $chan DEL $iif($2,$2,$me) }
  if ($1 == .delsop) { services sop $chan DEL $iif($2,$2,$me) }
  if ($1 == .delvop) { services vop $chan DEL $iif($2,$2,$me) }
  if ($1 == .owner) { mode $chan +q $iif($2,$2,$me) }
  if ($1 == .deowner) { mode $chan -q $iif($2,$2,$me) }

but you may want to add haltdef unless you want it to be seen on the channel and if you do it will mode then say it unless you use a timer. you will see it as command first then mode but others will see mode first then command.
