Simple Aerodynamic mods would out preform that entire list.
No aluminum crank shaft, not even single cylinder engines use aluminum crankshafts.
The 5.3L connecting rods are already as light as they can be. After market will tend to go heavier and stonger.
The 5.3 manifold is already very well flowing. The only way you might be able to improve on it noticeably is go with ridiculously long tube headers optimized for cruise RPM, which means they will end up being like 8 foot long primaries.
