I would not be worried about thickness: impact and compression resistance are not effected by the thickness of the (3") soft inner core, nor by the thickness of the denser-foamed mastbox: lamination material and its thickness (a few millimeters) are by far the main factors.
Longitudinal stiffness is, in theory, effected by thickness, but other factors are at play there (lamination, core, stiffeners, shape, etc..).
