I dunno do you think 5 additional watts would hurt anything? I mean its not like we would be jumping from 5 to 25 or something even higher
edit: Alot of ppl have done the Silverstar mod where you put the 65W hi-beam bulb in the low beam socket (low beam supposed to be 55w) and have been ok w/ it.
In fact what is the fog lights rated at? I have PIAA 510's in there that IIRC are 50w and they are fine. I dont think a 10w bulb in the license plate and dome lights etc. should hurt. Maybe someone can chime in.
