I intend to update the plug-in so that what is printed more accurately reflects the selection made on the product page – for example if you select a product variation and this changes the main image, then the changed image, showing the variation selected, should be printed. This will be in the next update.
I am not sure that this is what you require though. You would like a gallery of all product variations to replace the image gallery? Could you just add the product variation images to the image gallery? If you do not want the gallery to show on the product page you can quite easily suppress the output of the gallery with css.
