I sweated over the same problem and wondered about pulling new wire as well. Luckily for me the problem was elsewhere and it wasn't necessary to pull new wire.

I think it can be done. I wouldn't pull any wire without a string attached to it for the subsequent pull, and you would have to remove all of the blue connectors first.

The wires come in from the front of the shell and run under the cable channel in the center of the ceiling. Pull that first and you can get a good look at how it runs. You might also have to remove the fiberglass and plastic covers at the top rear of the shell, I found those easy to remove and replace.

My fall back plan if I were unable to pull the wires was to use cable channel to run on the inside surface to all of the fixtures. Again though, I got lucky and never had to pull the cable.

Good luck with this and be very methodical. The wire loops into a branch and loops back out again I think. All of this becomes clear when you pull the cable channel.
