So to get this right in my mind you have a "normal " attic space but also a dormer with that space between ceiling and flat roof being 150mm. If this is so I would perhaps cut the cable at the point in the normal attic space and join it their for easy access and inspection and run the new cable as one piece through the 150 gap so there is no junction boxes in this space which I assume is also filled with insulation.
