Technically it seems possible, however, it would mean duplicating every channel, pm/query, and (possibly) status window with a custom window using the format you're looking for.
Imo, a lot of work.
You can set up the right click in the channel or pm/query window to display an option which, when clicked would send the notice that you're wanting. This would be a lot easier, but the lines would still exist in the window.
