But then for the people complaining about the power that idle gear meshes consume especially, the constant mechanical efficiency loss of a overdrive unit would be unacceptable.

Apart from the primary reduction gear that exists on some gearboxes, what other gears are not strictly necessary? Can the differential incorporate a gearbox? Hmmmm....Food for thought. It would certainly solve the issue with >6 speed manual transmissions having a strange shift gate for gear 7.
