While Tim's adoption into the Wayne family will never cease to vex me, I always have liked the idea of Tim inheriting the company. Dick is doubtless a competent businessman, but it doesn't really fit him; he's a free spirit and his preferred form of responsibility is an intimate, personal one, face-to-face with the people he's helping. Tim, though... Tim's dad wanted him helping to run the family business at fifteen, and everyone said "of course." He's always been in the Blue Beetle vein, really, and between that and the ambivalent attitude he always had toward being Robin, him as the face of the Clan, the guy who holds down the day job and keeps the gear and the charity work going, would be a really natural evolution for him.
