Hmm, would be nice but not really necessary.
although I have thought of the Idea before of the Birth sign your born under have it's own Perk tree (that is if they went back to choosing your birth sign rather than willingly change it with Standing Stones)
Only by following your birth sign (putting perks in it) would it benefit you, would make more sense than automatically getting powers from something your born under unless you willingly decide to follow it's path.
In addition, the Birth Sign's already have their constellation design like the Normal Skill perk trees
Perks could be like :
Steed - Increase running speed slightly, Armor weighs less when worn, Horses have longer duration of Running, Horses are slightly faster, Stamina decreases slower when running, ETC.
