Static Aircraft Reduced Poly and Texture

[Verhängnis]

Is it possible that the 3d models of these could be reduced in Poly's abit and if possible simpler textures-or atleast have it as an option?

Reason being I populated my own airfield with static objects and a few German bombers and a Kondor + a few 109's and took quite an FPS hit (3-8 fps depending where you look and distance etc). Especially since they sit in hangars and I hardly see them anyway when flying, but they are nice to have as scenery during takeoff/landing and fast flights low over the base. It would be a shame to have to fly from such a boring place with no 'life'.
