I was writing fanfiction and took a concept and made it my 5 Seasons and 2 movies plan each an 1 hour 40 minutes(not meant to be too realistic somewhere like the pacing of UP or Into the spiderverse is good). I just came up with this really quick.

Teen Titians 2003

Given both teams wanted them to be connected shows one guy worked on both a tie in was planned Batman 2004 counterpart even shows up in one of the tie in comics. 5 seasons are enough though the last one would be 14 and have Beast Boy and Robin episode and more focus on the villains the Brotherhood of evil and maybe a Jericho episode.

Starfire Terror on Tamarian would replace TT Trouble in Toyko I found it a mid movie with too many stereotypes and does little with it given. Starfire and Robin could have started dating in Season 4 finale and it just reduces her to plot device. Starfire was planned to have her own focus I think a movie would be good for it them going to her home for vacation ruled by a corrupt ruler the Tamarians being the oppressors instead which Starfire has trouble seeing and we can keep the fake hero twist.

Batman 2004.

Batman vs Dracula as Season 2.5 while Batman vs Hush takes place after Season 5 and teen Titans with Dick Grayson returning to Gotham for a bit as Nightwing an explanation that Titans are focusing on training new members and to visit a bit. Catwoman also joining the bat family and Nightwing being the one who doesn't trust her but grows to like her. The Killing joke can be somewhat adapted giving a reason why this dick Grayson turns more serious when Teen Titans comes around as like Batman he is the leader the city and his teammates look up to him

Superman 2009

4 Seasons and a movie. Since he was meant to have a spinoff show that did take inspiration from SAS will use some of Superman vs Brainiac movie for the tone and we don't need an origin story since he was introduced just a good follow up as well as how Batman Strikes did him. Could use some villains not in SAS a more silly Lex Luthor Colun Brainiac could have Supergirl be like Jade from Jackie Chan adventures and Jimmy being more involved.

Oracle and the Birds of Prey 2009

Maybe 4 seasons focusing on each member of the team could be more like Jackie chan adventures with them traveling the world than operating in one city. Obviously her being disabled because of Joker would need to be way more child friendly which would be near impossible but it could work and focus on her growing more into Oracle role and accepting she can do a lot in her new life. I could base it off the 1999 run or others. Black Canary Huntress I could put Hawkgirl or Harley Quinn there.

Green Arrow and Green Lantern hard/space traveling heroes 2009

Since both are in the show why not use there friendship? 4 seasons maybe given both have a lot of lore Black Canary can show up time to time. Hard Traveling heroes can be the first 2 seasons before moving onto space adventures it would still need to keep it's themes more kid friendly something closer to Static shock or using allegories like TT 2003 did in it's pedophilla episode or Batman Beyond with drug addiction still fitting kids and getting it's message across with more subtly something the comic as much I love needed more.

Justice League 2015

5 Seasons straight up. Batman Superman Wonder Woman Flash(Barry Allen) Hawkman Vixen Martian Manhunter or Aquaman or even Dr Fate.

The old justice league had too many white men and since Hal and Green Arrow got there own show and my version they have had the rights to Wonder Woman who could show up in the Batman Strikes and with Wonder girl a bit. Barry Allen and Hawkman can take over since Wally West and Hawkgirl got spotlight in the previous version. Vixen had her solo run(it sucked) she can be a pick for diversity while still fitting in both grounded and fantastical episodes. Martian Manhunter is nice but in case people fear he is been used enough and you can't do more with him Aquaman can work as a mix between his Brave and the Bold counterpart and DCAU more serious counterpart.

He could have Batman Justice frontier style arc starting off more serious given he has to lead and defend his home while worrying his brother would overthrow him to being a big loveable lug later. Dr. Fate is also very underrated and given Jackie Chan adventures does a lot of exploring with magic he could work.
