Actually I think you can change the slide size in PPT -- and publish to that size.

We have used that strategy to create small flash animated pieces like the one here:

(we hijack the .swf file created for the slide) 

I don't know what it would do though if you wanted to use it in a final production (which is what I assume you want to do?)
