Machining 8:1 pistons to lower compression

Without having the pistons in front of me I do not know the thickness of crown material available to work with. My question to those with far more knowledge then myself is , Is it possible to machine the crown of 8:1 pistons Ruf? so as to lower to 7.5:1 Although I have been looking on line I cannot seem to find 7:1 or 7.5:1 pistons for the 3.4 cylinders unless they are in a PC set. It may require that I have to phone and these are considered speciality but they must exist without having to get made. I am looking at running with about 1 bar max. Would 8:1 be too much. Running with the CIS system.84 Euro 930 Kokeln intercooler, B&B heeaders and K2729 turbo. Thanks Rob
