My concern with doing that too far away from the VOR would be that the 0 radial is not always perfectly aligned with the magnetic North - there are a few airways around here which have about 2-3 degree difference in the radial defining them from the both ends. For example the outbound would be 183 but the inbound to the next VOR is 180. If I remember correctly, they get realigned if they're more than 4 degrees off from the magnetic North.
