I have similar situation, in my case I have a split boom, so I can use 
smaller diameter insert for the rotor and then fit the both boom pieces over 
the insert and maintain concentricity.

Another way of getting around it is if the rotor is mounted on the top of 
them mast you could have about 270 deg. rotation, make fixture in the form of 
letter J, where longer part of the J is made out of tubing that will fit 
inside the rotor opening, bottom part of J is long enough to clear the rotor 
body and short part of J can be made out of L angle and would have boom 
attached to it. In this case rotor is carrying extra load, so try to keep the 
bottom part of J as short as possible. If the rotor is mounted along the 
mast, you can still get about 150 deg of rotation.
