So I'm working on a Bubblegum Crisis reboot screenplay...

[classicdrogn]

Oh yes, the space model buma I used in Bubblegum Disaster is a canon design seen on screen, if only for a blink. (Not the Doberman, Mr. Big-Head whose designation I can't remember, who was tasked with maintaining the laser satellite and talks to Sylia after she goes all Lensman battleship against Moldiver Largo.) So is an undersea miner, for much the same reasons of easier life support and a sturdier frame to handle the dangerous environment and move heavy loads. Those were actual Stingray designed models IIRC.
