So I was curious as to what conversions were floating around at there that made
GW vehicles and fliers into variants. Not ones that improve on the model (so the bigger predator turret, the infamous extended length Stormraven, stretched scout landspeeders, different looking Leman Russ etc.), but the ones that make something new. So normally taking 2 or more sets and producing a new addition tot he arsenals of the far future.
My two favourite are the set back chimera making it more into a light tank/IFV.

And the 'stealth' marine flier.

Do you have any that float to mind?
