Okay, it has probably been done before, but just in case... In combined form, if you use both tanks as legs, you'll notice the lack of clearance between the two, forcing Bruticus to do the split. You can gain clearance and get leaner legs by just flipping the inner tank threads to the rear. Or both the inner and outer tank thread if you prefer them to be even slimmer and more symmetrical. It looks way better and improves poseability.
