The easy option Is 10mm longer studs , this way you can fit with out removing hubs , you only need to remove calipers , discs and one of the rear shoes per side . You can still use standard nuts too with out spacers , the perfect solution . I guess fitting is a couple of hours .
I have gone into longer studs and you can't just say you can run 5mm spacer or what ever with standard studs , it depends more on the type of nut you are using , if your on standard nuts then you have more leeway than with 60 degee taper nut on an aftermarket wheel ! I would never use spacers on standard studs and 60 degree taper nuts with out going with longer studs !!!
