Toei should have just asked Toriyama to write some more detailed Dragon Ball lore expansion stories for them to animate like Mutaito/Roshi/Tsuru vs the Demon King, Kami-sama's arrival to Earth, previous Dragon Ball wishes/the wars that were fought over the, how Goku was living in mont Paozu for twelve fucking years, the Tenakichi Budoakais the heroes didn't participate in, Vegeta under the rule of Freeza. Anything to milk the series if they wanted to milk them. No point in doing a remake when they'll get all the original content washed and censored by new TV guidelines.
Then again, perhaps it was better to leave all those things obfuscated to keep a bit of mistery for the series.
