Believable dream team(its possible) - First thing, fire Yamamuro.
Series Director : Hatano Morio - One of Toei's finest directors. He is a Yama'uchi fanboy and his style quite resembles him. I like his style. He also has enough connections, so that'll be helpful too.
Series Composition : Tomioka Atsuhiro - Fast scriptwriter. Quality exposition and battle scenes writer as well.
Character designer/Chief Animation Director : Tate Naoki - Animation-friendly designs. Less complicated, but full of life. It'll be great.
Storyboard : It all depends on who the director and production assistants can get. But, if they can assemble something like this, it'll be good.
Hatano Morio, Chioka Kimitoshi, Karasawa Kazuya, Shida Naotoshi, Kaizawa Yukio, Kakudou Hiroyuki, Ootsuka Ken Kamatani Haruka(her combo with Watanabe would do wonders), Tanaka Yuta(best guy)
Except Shida and Ootsuka, all of them are good directors too and they'll handle their own storyboards.
Animation Director(s) : Watanabe Koudai, Hayashi Yuuki, Oonishi Ryou, Yashima Yoshitaka(fast guy) Karasawa Yuuichi, Tate Naoki(if needed), Takahashi Yuya
Key Animator(s) : Watanabe Koudai, Hayashi Yuuki ,Oonishi Ryou, Shida Naotoshi, Takahashi Yuya, Ota Kazuhiro, Kuroyanagi Kenji, Yashima Yoshitaka(fast guy) Ootsuka Ken
I can go on. Give them at least a year of production time and I guarantee this team will most likely produce wonderful results and
Dragon Ball will no longer be shit.
Not possible dream team
Series Director : Ryoochimo - Great animator turned director. Actually, webgen animator turned director. His connections will get us abundant webgen talent cause of his contacts.
Series composition : Tomioka would be alright. I guess.
Character Designer/ Chief Animation Director : Ryoochimo - Lovely stuff. Animation-friendly. A necessity for good animation. His designs have little to no linework at times which I love.
Storyboard : Since Chimo is SD, it'll unquestionably have great directors. Some of them would be:-
Ryoochimo, Yamashita Shingo(of course), Kobayashi Hiroshi, Matsumoto Norio, Natsume Shingo, Matsuyama Masahiko
Animation Director(s) : Yamashita Shingo, Fujisawa Ken'ichi, Nakayama Ryu(action animation director) Kawano Tatsuro, Kameda Yoshimichi, Oda Gosei
Key Animator(s) : Fujisawa Ken'ichi, Yamashita Shingo, Matsumoto Norio, Kameda Yoshimichi, Oda Gosei Fujii Shingo, Nakayama Ryu, Arai Kazuto, Kobayashi Naoki
There are more talents I'm forgetting. If someone produces this it'll be great. But, this is too good to be true.

The sakuga fest would be uncontrollable.
I would let Studio Bones handle the production. Keep in mind, most of them are freelancers and studio has nothing to do with quality. The Bones environment would be just good to work at.
