You can print basically any circuit you can design and fit on a two-layer board. So it's certainly feasible.
However, if you're thinking of having a V-One on-site at the fights to replace something quickly, it's not that quick. I mean you'd have to allow time to print and IDK if have enough time between bouts. Maybe you would... I know almost nothing about mech fights.
Very interesting question! I'm curious if that's what you're thinking of doing.
