The thought of getting a falconry license as an easier mean’s to obtain a raptor will not set well with many falconer’s myself included. Falconry is defined as the pursuit of wild quarry in it’s natural state and habitat with a trained raptor. Any goal other than this is not falconry. Hunting should never be considered a byproduct of falconry but the essential goal of every falconer. You mentioned being involved in rehabilitation and it sound’s like that may be the right path for you. I am sorry if I come off as rude but this is the simple truth. Falconry is a hunting sport and anything less is unacceptable in my opinion.
