This is a general response to the thread.

Before investing further efforts in this area, please do realize that raw
pointers do not inherit from one another. "T *" IS-NOT-A "T const *" or "T
volatile *", and "Derived *" IS-NOT-A "Base *". A const reference to "T
const *" does not bind directly to a "T *", it binds to a temporary copy of
type "T const *" using the standard pointer conversion. This is exactly what
shared_ptr does, too, except that it uses a user-defined conversion, for
obvious reasons.
