Conversion of animated cursors (.ani) to a PNG graphics (.png) is probably possible, but only one frame from the animation will be saved. Imagine the .ani file as a series of pictures (frames) that are saved together to create the animated feel. So from a single .ani file, you could in theory export several images (essentially ani to png conversion) and save them as .png files, or any other similar graphics files.
