Yeah, Driver would've had to be moved to MCU by now, since I don't think there's much downtime between Jim's recovery and his retirement. But most places list his first appearance as Gotham Central #1. I don't remember, but they might've even said something about him not knowing Jim too well? The only other blond guy I can think of is Trey Hartley, who fits even less than Driver.
Okay, Comicvine has an answer for us. Batman 587 lits both Joely and Vince as appearing, so it looks like your first guess was right.
