Not possible in the same document, although on a document-by-document
basis I would recommend the use of file local variables.

That is a very good point.  I had originally started to implement this
parameter using a header argument, but then decided that it didn't make
sense to implement a multi-block parameter using a header argument.  Now
that you mention this however I do agree that a customization parameter
is even less appropriate.

Given that header arguments may be set on the file and subtree level, I
suppose they do offer the range of application appropriate for this sort
of parameter, and they are more likely (though not guaranteed) to have
their value present in the buffer.

I've just pushed up a change converting the `org-babel-noweb-separator'
customization variable to the :noweb-sep header argument.
