How Force $nick to display my custom nickname

Hi, I have this problem. I would like to force the $nick identifier to show a custom nickname.
For exapmle, I have made a custom CTCP event (ON *:SIGNAL:CTCP:) and I like to force mIRC to show as $nick a custom nickname, instead of my nickname:
Example:

Code:

ON *:SIGNAL:CTCP:{
  echo -s $nick
}

My nick is [R]u[F]y, and when someone CTCP me, my mIRC Show this:
[3:56:07pm]•CTCP: [R]u[F]y (N/A) TIME
[3:56:07pm]•CTCP: reply: [R]u[F]y (chaos@IRCd-IT-9AD91782.net24.it) TIME Fri Sep 30 15:56:07 2005

And it was wrong. Can I force the $nick identifier or other identifier to show whatever I want?

Just dont use the $nick identifier, for example 'echo -s NotMyNick rest of stuff here' instead of 'echo -s $nick rest of stuff here' ?

u cant override any identifiers, they are what they are.
