I don't like this idea.
I would much prefer it if you could simply bind a command to any key and edit all menus, that way you can hide/stop the options dialog from opening, but it's still included in the exe.

Eg:

Code:
; -b stands for bind.
alias -b S { echo -a You hit S! }
alias -b Ctrl+S { echo -a you hit Ctrl+S! }
menu menubar file {
  ; Your own file menu here.
  &Connect: server
  &Disconnect: disconnect
}


This way you can remake the mIRC menus so they open your own options dialogs, of course this would be much more useful if you could edit the mirc.ini while mIRC is running.

Being able to Add your own menus would also be a plus:

Code:
menu menubar mynewcoolmenu {
  ; ...
}
