The problem here is you are trying to support additional load from people/ luggage, not the self weight of the rear of the car. If you put a steel beam into a brick wall, you can preload the beam so it doesn't deflect when the weight is taken up, but in this case the "live" load is much greater than the "dead" load of the rear bodywork.
If you jack up the rear before supporting it, you still have the same problem with cracks if it deflects under load.
The solution is stiffness in the supporting structure. This is best done with triangulated shapes and members that have more depth than width... but on reflection, you're not going racing with this, so a bit of extra weight probably doesn't matter!
