Note this picture below, you'd have to remove 1-2 of those seats behind the cab in the first place to even think about putting in more seating - and that's without taking into account that the floor of the upstairs is raised above the cab/accessible seating area, so any space behind that (i.e where the luggage space is) is nowhere near big enough to consider seating (2nd link).There not going go be room for much to be fair
