Yes, except for that pesky problem that the pyramids were often built on high plateaus... well above the level of the Nile.
There are no such canals at Giza, as we find at Aswan. Take a look at this picture I took. I'm standing just southeast of the Sphinx, which can be seen in the bottom left of the picture. From this, you get an idea of the considerable slope up the plateau to the pyramid.
Suffice it to say, there would have been no canals dug here that wouldn't still be visible today. And, although the Nile does flow "backwards" (from south to north), it does not, as far as I know, extend that particular trait to flowing uphill.
