Thank you both (gariotin and linweseregon) for the great comments. One of the things that went a long way toward the inspiration was a screen cap of one of the deleted scenes in the Houses of Healing, showing Aragorn with Faramir (hey, I would have given up seeing Sam's wedding in order to have had those scenes put back in).
I've got a few ideas floating around in my head, and hope (after some more research) to be starting on another story shortly.
