>>23383669 (OP)I got a lot of ZZ feeling from GQ in a good way.
I'd have Machu and Nyaan go on an adventure with the Qx and the glider they were going to buy for Shuji, exploring different colonies.
I'm one of the few weirdos on Earth who likes the Moon Moon arc in ZZ, for being pure 80's sci-fi adventure. Just an imaginative premise about how life might evolve in outer space, and the ZZ crew encountering that adventure.
G-Reco also has a similar feeling when they go to the Venus Globe, just a completely far out and fun sci-fi premise.
Machu and Nyaan would explore the solar system and fight in monster of the week mobile suit battles, Nyaan would get a new mobile suit of her own (something really unique to suit her), maybe even expand the Clan Battle premise, where the two of them are traveling to different colonies to participate in Clan Battles for money.
They could be chased by different factions, bounty hunters, etc.
Their ultimate goal is to find Shuji.
Watched over by Amuro.
An episode where they visit Char and Lalah, and maybe Char joins them for a little while (I wouldn't have too much Lalah - she's an important character to me and I want her to be mysterious - so maybe she has business at home)
Follow up on all the major characters like Chalia, Xavier, Comoli, Artesia, etc. etc.
Slight implication that the GQuuuuuuX allows Machu and Nyaan to travel between different universes. So they're not just exploring the solar system, they're exploring multiple versions of the same solar system: although keep this subtle. It's not a completely important idea, and I'd want a sequel to feel a little more grounded (even if it's secretly a crazy dimension hopping story).
Neither Machu nor Nyaan get a love interest, and they remain MAVs throughout the show.
At the end of the show Shuji (who is really a kind of Newtype spirit) agrees to incarnate as Machu's child.
This leaves Machu on a quest to find a (real/physical) husband.
