Oooh, I've got a weakness for crack-treated-seriously sort of scenarios - I'd absolutely go for this! I think it'd make for some fun contrast between the factions, too, where Megatron is actually being very straightforward about what he wants by Decepticon standards and Ratchet doesn't realize it until some other Decepticon yells about it (probably Starscream, because I think that's funniest).
