Many canards have CG's completely ahead of the main (rear) wing. If this is the case, the heaviest pieces of the airplane (the engines) are possibly still *behind* if not right on the CG. I wouldn't be so quick to say that the hypothetical B-17 canard is "noseheavy."
Technically it could be made to work given the proper CG and area ratios between the main wing and canard, as well as the proper moment arm on the canard.

No,
The CG for an airplane is typically about 1/3 of the way between the leading edge of the wing and the trailing edge. A few planes have horizontal stabilizers that create lift and change things a bit, but this plane is way too nose heavy.
