As a reference, China has been doing this a similar project to interconnect the North (think Beijing etc) and South (think Shanghai) water system. Heck, they have been doing it since hundreds of year ago [2]. So I guess there is a precedent.
Based on this thread, I would guess that a large amount of the problem will not be an engineering one, but political and social one. Constructing such a large mega project to divert would require a national unity and tremendous will to 'sculpt' nature.
