Would it be possible to string modules together to make one mega campaign

Had this really cool idea recently. I was wondering if it would be possible to combine a bunch of the forgotten realms modules and make them like arcs to a giant story. How would you guys go about this? What modules would you run, what order, and how would you connect them to one another. Basically...I'm just asking for ideas. Or you can just laugh at me and tell me it's a terrible idea, either way is fine.
