If I understand this correctly you are wanting to place them on the rear molding right under where the hatch's latch is? I could set something like that up but don't prefer it, I like to hide the LEDs, going that route would have them too much in the open and it would be harder to run them due to the wire having to go somewhere. It's a shame you aren't closer, it's so much easier to do custom work when I have the car in front of me.
There might be a way to fold the carpet back on the sub box to let the light from a ZX3/ZX5 kit shine through but that would be some custom work you would have to fiddle with, I tried and couldn't find a way to do it without doing some kind of work on the sub enclosure.
