Gizmos.GUIDrawTexture - draw texture below?

I'm using Gizmos.GUIDrawTexture() in DrawGizmo to draw custom complex textured object in the scene editor.

Everything's work fine, but the texture is drawn on the top of all my GameObjects.

Is there any way to draw it below everything? I need to see other game objects (particle systems).

The only temporary solution I've found so far is to draw a texture using semi-transparent material so I can see through it.

PS: I can't use OnSceneGUI because I need an object to be drawn always, not only when it is selected.
