I do agree with that. At least I'd would much rather see Dick on the team without Bruce being involved in the story he's in.
Honestly, there isn't any reason Dick couldn't become a member if they expanded the roster of the JL. (Something like Justice League Unlimited.) If they did that then older members could make a return and maybe they could add some new ones at the same time.Of course, it probably helps that there are older members of the team who I would rather see back then I do seeing Dick on the team.
