Hmmm, I'd imagine it'd be possible with Mortscript.
I've never actually written any scripts for it but from what I've read, it executes a series of commands you tell it to, such as button presses and scrolling to a name, etc.
It seems all you would have to do is program in the steps that you would ordinarily do to text Rodney, assign the script to a key, and voila! a new text message to Rodney
