Answer 1

I got the solution myself.

First, create your new template files. I copied the originals, and created view-diff.phtml, and media-diff.phtml in the same directories as the originals. Once that is complete, edit a product, and go to the “Design” tab. In the “Custom Layout Update” text area, you can put the following, which will redefine which templates it uses for that product

<reference name="product.info">
    <action method="setTemplate"> <template>catalog/product/view-diff.phtml</template></action>
</reference>
<reference name="product.info.media">
    <action method="setTemplate"> <template>catalog/product/view/media-diff.phtml</template></action>
</reference>

Thats it!
