Yeah, honestly the idea of a robot green lantern is cool. they have robot powers and light constructs, powerful combo

Wait there is a green lantern iron man? did marvel and DC do a crossover

They did Marvel vs DC event in the mid late 90s, then merged together as the Amalgam Comics, then they separated away from each other, but it's still canon as a another earth in the DC multiverse, so you can find Iron Lantern one day, or Super Soldier, or Dark Claw.

Wow, now i wanna see what a white lantern galactus would be like
