What could a 1920 infrastructure program do for aircraft production?

Could the postwar infrastructure program include upgrades for aircraft manufacturing?

The limited window leaves little scope for direct upgrades, but it could improve access to aluminium, oil, and other necessary materials.

The scenario allows only the period from 1920 to the Washington Naval Treaty in 1922 to authorize the work. That limits the proposed aircraft-manufacturing improvements. Better access to industrial inputs is the practical option. Aluminium and oil are the named examples of supplies whose availability could be improved.
