A "spiritual tradition" you say? Seems to me like Force Sensitive it back to what we're looking at instead of some Martial Arts tradition.
Could create some kind of Force Tradition that is oddly centered around the character following that tradition not actually having UtF trained. Perhaps a key talent to the tradition is one that allows you to use "trained only" aspects of UtF and maybe by having you count as having UtF trained but without actually getting the normal +5 bonus for training; maybe a +2 competence bonus which of course wouldn't stack with Skill Focus. Additional talents to this Tradition are likely to be "skill substitutions" where you are actually using OTHER skills in place of UtF instead of the other way around.
