yeah as long as you are just handling and not pulling off shed then you shouldn't harm your snake. I handle my BRB's when they are blue on a fairly regular basis since cage maintenance has no respect for shed cycles 
The issue with handling while in shed is the snakes can become more irritable and if they are milky eyed or blue then they can be very defensive. My BRB's are very mellow and I pay close attention to how they behave/react. As a result I have never been bitten by them and the closest I have gotten was having Brunhilde go into a defensive pose and slightly open her mouth once.
Main thing I would be worried about is if your BRB is shed blind at the time of the shoot and decides to bite someone because of being scared.
