It would certainly be possible.

The question would be when you'd use it. I can only think of it as useful if
you have a multithreaded application and you run curl_easy_duphandle() for
each new thread to avoid a series of identical curl_easy_setopt() invokes in
every thread.

Or?

Oh yes, we should probably re-arrange the internal structure then so that we
can more easily keep track of what data that should be duplicated and how.
Duplicating a handle could only be a matter of cloning data and options,
internal state info and things like persistant connections cannot be
transfered.
