Wow, I don't like that bracing at all!!!! Just a suggestion to ponder. How about if it were a "two rail" brace, the bottom rail following the trunk floor and attaching into the other structure where the cross bar is on the bottom, then a second bar about at the peak of the trunk floor and going to where the top cross brace is? The force would still be moving into the passenger compartment, but it would seem the lower bar would also bend down from the point where the top bar welds to it to the back of the car????
