Agree JT, this sounds a bit dodgy. Denti, do you mean that you have 8-10 aeroplanes with different MTOWs or one aeroplane with 8-10 MTOWs? My employer has done this in the past, but the reduced MTOW (one only) was promulgated in the AFM and not changed at the drop of a hat. Obviously though, the cost of doing so was made up in reduced landing fees.
