In terms of the options here, I'd love to see them include some DCAU shows. I vaguely remember watching Batman The Animated series on classic Toonami and it would shake up the lineup a bit with having some western animated shows too. Outlaw Star would also be pretty neat. I wasn't huge on it after seeing it for the first time on the revived block. It was pretty interesting and engaging, but I don't think it lived up to its hype for me. But it's still an iconic part of Toonami classic, so that would be fitting. Big O would also be pretty cool since I've wanted to check that series out for ages.
I like the idea of featuring shows that weren't on classic Toonami but should have been. I'd love to see Trigun and Slayers on the block, even if the latter would be too difficult due to Crunchyroll. While the main appeal of Toonami Rewind is to see classic shows from the block's history, I think that showcasing older anime that wouldn't really work on Toonami proper would still work. Ideally, this would be easier to do if they had more than one day a week, but hopefully it will be successful enough to do that down the road. The original Bleach series would also be a great fit. Maybe they'll save that for main Toonami block instead, but having Sailor Moon, DBZ Kai, Naruto and Bleach airing together would certainly cover major shonen and shojo titles from over the decades. They may want to get the Thousand Year War arc instead of reruns of the original series though.
