Here's where I am with mods on mine. The first thing I did was replace the yellow sheath with the correct one. However I cut it to make it more accurate length and it ended up coming undone on one end, so now I'm waiting on a replacement. I also added electrical tape over all the molded tape on the cables.
Dislodged the breather hose and moved it down a few inches. Painted it moss green and lightly weathered. I plan on replacing part of the loom with the correct breather hose, fuel hose segment, and Neutrik connector soon.
1 inch insulation pipe foam and 6mm wetsuit neoprene, lightly weathered with brown paint. I cut the length to 10 inches. Painted the brackets and screws for the ALICE frame flat black. Lightly weathered and sanded the shoulder pads as well.
Replaced the fake, plastic cable clamp with a real 1.5" P-clamp. I attached it using the molded plastic screw from the fake clamp instead of using a real M5 screw and washer. I cut it and trimmed it down and painted the screw in the center black.
Added the correct clamps to the red cable. I still need to trim off the excess material from it. I painted the head of the copper wires silver and lightly weathered. I still need to add copper tape to the wires, followed by heavier weathering. To get the mini clamps on the copper wires, I cut the wire underneath where the clamp is supposed to go. I then slide the clamps on and super glued it back together.
Removed the white diffuser for the power cell lights and replaced it with a black Hobart welding face shield. I kept the clear plastic in the front. Using a black lens seems the most accurate for Afterlife. I'm not using any diffuser for the blue lights.
Added blue electrical tape to the cable on the left. It's supposed to be blue, not black. Also painted the screws on the bumper and the bottom of the pack flat black.
Replaced the red lenses on the cyclotron with black Hobart face shield. Removed the white diffuser and replaced it with a sheet of paper behind the lenses. It was not fun having to pry apart the cyclotron lid. It requires breaking off several pins that were permanently glued. I don't know why Hasbro made this the one part of the pack that is inaccessible.
