New Gundam Story Idea

While typing up some stuff for Mobile Suit Gundam: Beyond War Chronicles, my Gundam fanfiction that continues the Universal Century timeline, it came to me that I should consider an alternate universe setting after I finish said storyline. What hit me was the idea of a G Gundam storyline that takes place some odd 20 years after the events of the series. The main character would be a hardboiled detective who was also secretly a Gundam Fighter. He is sent to Earth from the Neo America colony in order to find several missing scientists from around the colonies. He eventually crosses paths with a dark organization, their dark goal being the revival of a certain destructive weapon. What do you think?
