Not quite, Boltzmann gas theory considers

1) Particles of gas are spherical and always repulsive
2) Distance between particles is higher, then the size of particles
3) Energy between particles is exchanged by elastic collisions only, so that only longitudinal waves can place here.

In AWT model all these assumptions are violated for vacuum. Only Aether can be modelled by ideal gas - observable rest of Universe must be modelled by density fluctuations of Aether.
