It would seem that in order to come to a solution, you will need to provide some more information about the loads, conductors and how they are served. It is possible that the solution is not to pull a parallel neutral, but to mitigate the harmonic problem at the load, change the distribution groupings or determine a malfuntioning load. A parallel neutral is a band-aid solution and shouldn't be entered lightly.
oh, and please don't beat up the engineers. Don't be surprised that the next time you look in Section 16050 of your specification, that it doesn't say that you have to bring donuts any time the engineer shows up.
