I'm not sure why he'd need to recruit people. There's already a pretty large Bat-family, isn't there? Bruce-Batman, Dick-Batman, Red Robin, Batwoman, a Batgirl or two, and that Knight and Squire team in London. (I want to call it "Londinium" like in the '60s series.) So it's already kind of a readymade franchise.
Besides, how's he going to find new people worthy of donning the mantle of the bat? Host a reality show? Who Wants to Be a Superhero, Gotham Edition!
