Not possible : the Valgrind tools are not "stackable". Note that something like 2 years ago, I started to work on a patch to callgrind to have it recording the allocation/de-allocation together with what it can record now. This would reasonably fullfill your usage above (i.e. have callgrind+massif). Never finished :(.
