You could modify image-type-available-p to do it on the fly:

(defun image-type-available-p (type)
  "Value is non-nil if image type TYPE is available.
Image types are symbols like `xbm' or `jpeg'."
  (when (and (boundp 'image-library-alist) image-library-alist)
     (init-image-libraries image-library-alist)
     (setq image-library-alist nil))
  (and (boundp 'image-types) (not (null (memq type image-types)))))

This would have the effect that the user could try different settings
of image-library-alist and just use the normal image functions to
have the changes loaded on the fly.

The above patch guards against that to some extent, but explicitly skipping
those elements which are already in image-types is a good thing.

As you see, I also changed the variable to image-library-alist -- there's
no need to emphasize that this is w32 specific (other systems may need it

Finally, I propose to specify the alist as arg to init-image-libraries;
there's no need to "pollute" the C code with a Vw32_image_libraries_alist
