You will get little if any compression without stators - a compression stage is rotor+stator, All you will do is stir the air up somewhat and I would think that all the rotating blades apart from the first row will be operating in a stalled condition. As a matter of interest how will you calculate compressor blade profiles,blade twist,chord and height? Do you know what compressor stall is? To be honest I think you are operating well outside your knowledge of axial flow compressors or you really would not have posed the question that you have.
