I got around to installing the combox today. I ended up just moving the pins as the parts for PnP were getting expensive for very little benefit. It was only 10 pins to move. E70s are easy to move pins as the TCU and MULF wires are long enough to reach to the combox. Some of the E90/E60 wires are not long enough reach and thus PnP adapters makes mores sense for them. Also, I was able to remove the extra fiber from the most bus and save the expense of the fiber terminator. Just use a flashlight to find the ones you want to disconnect, pull them from the center of the bus, and move the leftover fiber over to fill in the gaps and close the ring.
