So, I've been daydreaming of a mod to create stick-on greebles. It would work more or less like the sticker mods out there, but the models would also have normal maps. These parts would be physicsless and non-functional, just cool looking little details such as tank raceways and other little pipes and bumps. Ideally these would be able to be attached to parts of various sizes and shapes.
Can anyone with more knowledge say whether or not this idea is actually possible in KSP?
