3:36 Slight correction there. Exia's GN Blade's ability to penetrate GN Fields is not because of it being a "physical" sword, but because it is coated with "GN Particles". Same method is used later on in season 2 when they coat other weapons like GN Missiles / Egner Whips with GN Particles to allow them to penetrate GN Fields as well. 12:35 Avalanche and the Avalanche Dash packs were both manufactured and equipped onto Exia in 00V. Setsuna piloted Exia in these configurations to destroy meteorites. So it's not just existing in design.
