BB for XTR/M900 with double chanringTosh

Did anybody experience putting the XTR/M900 square tapered crankset on roadbike with double chainring? Please advise me what spindle length is appropriate for this setting. I put the crankset on 103mm/WorldClass BB which is compatible with Shimano taper and resulted 43.5mm chainline for TRIPLE setting. From this measurement, I suppose I need much shorter spindle. Possible solution might be using Campy 102mm BB which has smaller cross section but I am not sure if XTR/M900 crankset can be installed on it without striking to each other.
