I hope it continues to do good, it's really cool
An action block would be cool, but I'm on the fence on whether the Timm shows belong there just yet. They are 30, 25 years old but I do worry they would overshadow more of the older action shows that don't get aired as much. I would prefer if it was just shows like Jonny Quest, Space Ghost, Herculoids, He-Man or the Filmation DC cartoons
More anime would be interesting too, but nothing from the anime boom onwards. Stick to shit like BOTP, Astro Boy, Gigantor, or weird stuff like Prince Planet. Don't make the mistake Toonami did with selling a "throwback anime block" but using crappy modern dubs, Gatchaman has a more modern dub from 2004 but that is not what their audience thinks of when they see those characters
Disney would be amazing but Neal Sabin has said that's probably a pipedream. Weigel... possibly has some connections at Disney, they’re able to show 20th Century Fox shows, but who knows whether those are legacy deals. Terrytoons are much more likely, they've been trying and Weigel has a good relationship with CBS, only problem is CBS doesn't give a shit about Terrytoons
The Cartoon Lost & Found show they've been talking about for a while sounds fascinating, right now the only show I've heard'll be there is Courageous Cat and Minute Mouse but there's a lot of weird shit that would fit in H-B's catalog alone, something like the "Look What We Found" block
