I actually have my own prototype implementation (attached) that I used to
test my ideas of how unique_ptr<T[]> and unique_ptr<T[N]> should behave with
respect to conversions between them (modeled after shared_ptr.)

It's however a prototype; meaning that it relies on C++11 features, does not
optimize out empty deleters, has no tests. I used the libc++ test suite to
test it, but that's not suitable for Boost.

It didn't occur to me that Howard has already written the test suite in a
more suitable form. :-)

I intended to eventually bring this up to production quality and make it
boost::unique_ptr, but couldn't spare the time.

That exactly what I did too. :-)
