I can’t answer the direct question, but depending how you stack people bikes and kit, I could get 3 bikes, people and kit in my old astra estate and my current (new model) focus estate. Bikes in inverted, seatpost out and front wheel off.
Reason I didn’t get an Astra sports tourer when I changed between the 2 is the sloping rear roof and the slightly shorter load bay meant you couldn’t get 3+3 in.
Knowing how the focus hatch is laid out I think you’ll struggle to get bikes people and kit in all together. They share the same floorplan virtually, and you’d be pushing it to get a bike in on it’s side even wheels off and keep the small rear seat usable. It would swallow 2 no bother though.
Can’t you get a focus estate?
