Don't expect much increased fuel economy from reducing weight (if any). At highway speeds added weight is a pretty small part of the fuel economy equation, though certainly non-zero and if you're aiming for max, I'd say go for it.
You'll probably mostly notice better acceleration and probably better handling but at the expense of greatly increased cabin noise and ride harshness.
