custom less than operator? to_python_converter for multiple destination types?

So, I'm wrapping a class that defines "<" as an internal class with a 
bool operator() like so:

struct Baz
{
        struct Less
        {
                bool operator() (const Baz& a, const Baz& b) const;
        }
};

Inconveniently, it also does NOT define operator < in Baz. How would I 
wrap this to make Baz objects in Python use Baz::Less::operator() as the 
 < operator?
