I like a lot of what you're saying, but this is a heckuva assumption resting at the core of your argument. I agree that this is true in a perfect world, where the game balance is ideal and everything is properly costed, but our evidence thus far seems to demonstrate that this is not true.
A Tempest Squadron pilot is not as equally valuable as Rookie Pilot, despite their identical costs. A Blue Squadron pilot is more than 4.7% more powerful and efficient than a Rookie Pilot. These may be minor aberrations, but they matter--especially at higher levels. If all else is equal, the build that can most take advantage of these points will have an advantage.
The thing is that incorporating these aberrations wont make or break the model and will take more work to basically just give you the same results.
In any given match the winner is more likely to be determined by a disparity in skill (and yes list building itself is an important skill) than a ~10% imba between the baseline ships. Most of the time any perceived weakness of a ship is due to the ship not living up to preconceived notions on what makes a good ship rather than an objective analysis of the ship itself and what it brings to the table.
NOTE: I'm not saying you can take a random collection of ships and upgrades with no consideration to strategy and expect to win. I am saying that more ships than the current supposedly blue chip choices are in play if they mesh with your over all strategy. And the only way you can tell for sure if those ships mesh or not is through hard earned experience.
