I would budget your bauxite consumption to be near or slightly less than your E-3 cost if you can clear it within the same number of times.

E-4 cost me 5,525 bauxite in total at 13 runs with 5 Reppu and a Reppu Kai across Souryuu, Akagi, and Kaga. 21K should be enough for both maps if you don't get unlucky with RNG in E-4.
