So the multiverse gods somehow land Paul Atreides and Anakin in full Darth Vader mode in the Lensmen universe. They come across Kimball Kinnison as a fully powered 2nd Stage Grey Lensman. They try to control him to do something or other - can they?
I don't think so - yeah, it might be a stomp. A second stage lensman was estimated to be able to stun everyone in the North American continent, for example. They had awesome shields.
Yeah, it's a stomp. If Kim is nice, he will just send them on their way. Maybe he will fix Darth and make him sane.
