In a campaign I'm running, I had a character who comes from a place where everyone who use magic gained it from their blood. So I came up with a lot of /sorcerer(s), but I haven't really flushed them out.
-Blood Priest (Cleric/Sorcerer) * bless with bloodline power by whom they worship
-Reaver (Paladin/Sorcerer) * Devoted to their Bloodlines power source
-Chronicler (Bard/Sorcerer) 
-Bloodhound (Druid/Sorcerer) * wildshape limited/expanded by bloodline
-Blood Warrior (Fighter/Sorcerer) * no spell but they gain abilites from their bloodline
-Blood Saint (Monk/Sorcerer) * uses ki to focuse their bloodline spells
-Wild Warrior (Ranger/Sorcerer)
-Blood Trickster (Rogue/Sorcerer)
-Unblessed (Alchemist/Sorcerer) * their bloodline powers are so faint they need the the aid of alchemy
-Blood Knight (Cavalier/Sorcerer)
-Bloodslinger (Gunslinger/Sorcerer) * uses grit to cast spells
-Headhunter (Inquisiter/Sorcerer)
-Bloodmage (Mangus/Sorcerer)
-Shadow Warrior (Ninja/Sorcerer)
-Blood Sion (Oracle/Sorcerer)
-Warlock (Summoner/Sorcerer) * make a pact to gain bloodline powers
