Unless you also sacrifice binary compatibility, it's not possible.
What it is possible is to have one allocation instead of 2 (the object
and its dpointer), that's already been worked upon with a custom
operator new, check the patches on gerrit.
Anyhow this is entirely orthogonal to the original problem at hand:
ownership. We need to support the case of objects created on the stack
(not owned and owned).
