I doubt Captain John would ever be Jack's replacement. If anything, I think the producers would want to move away from having another 51st century time agent as a member of the team, in order to take the show in another direction. But someone has to fill David Tennant's shoes when he leaves next year, so finding a replacement for John won't be any harder.
I do think Gareth becoming a leading man in Torchwood is a realistic possibility but he does need to get that 2nd significant role in the next few years and rise his profile. Even David's career started off as being supporting cast only and like David, Gareth potentially has lots to offer as an actor as he gains more experience.
