Here's a thought...
What if DC really had tried to make the Titans into an X-Men-sized franchise?
While I do think that Peterson's influence on tone was detrimental to the title... he did have some good ideas about strengthening the Titans as a franchise by bringing Deathstroke back into the book and giving the Titans a second team title.
However, I don't think Team Titans was the best way to go.
Looking at Marvel's tactics with X-Men, especially in the '80s and '90s, they would periodically re-invent the line-up of the X-Men and launch new teams by splitting off some of the popular characters into a new series.
Excalibur used Kitty, Nightcrawler and Rachel.
X-Factor was the founders, which included Cyclops, someone that had been in X-Men for forever.
Imagine if, instead of getting a team of unknown nobodies and an alternate reality Terra... we got...
The Titans West team that Wolfman had been planning, but with Cyborg and Changeling being the transfers to the new team.
I've looked at his
original thoughts for the line-up, and after adding Changeling, I would drop Diah H for two females: Bumblebee and Dr. Light (Kimiyo).
This would've given a line-up of:
Cyborg (leader)
Changeling
Bumblebee
Red Star
Thunder
Lightning
Dr. Light II
A much stronger pull than Team Titans, I think.
And since DC and Marvel are always taking cues from each other...
A second Titans spin-off team could've been the Fab Five (ala X-Factor): Nightwing (leader), Troia, Tempest, Flash and Arsenal.
As for who would remain in the main book, they'd still have Starfire (who would naturally become leader), Raven, Pantha, Jericho and some new members.
Wolfman could've been already building up the new members to replace Changeling, Cyborg, Nightwing and Troia... if they had been thinking about expanding like this.
And constant crossovers with the other two books would ensure that they would still be making regular appearances.
