Not just that.

a) You'd have to get the nut back _exactly_ in the balanced position.
   As you probably know, if you've seen one end-on, there's usually
   a drill bit mark on the face of the nut from final balancing.

b) How are you going to hold it while you torque up the bolt?

c) [the killer] If the nut has been off for a while, the blades may
   have contacted the housing.  This will have altered the balance,
   and will quite possibly have filled the immediate environment
   with metal splinters.

BTDT.
