There was a thread a while back about motion and parallax, and Colin Holgate shared a stack or two with a demonstration of that effect. On my blog, I posted an example of Malte Brill's technique of using a scroller to move large images along a single axis, which could likely be expanded to move in two axes. But I imagine that adding the additional "half D" of scaling an image at the same time will depend significantly on how large your displayed images will be.
LiveCode has never been that great at moving full-screen images around, and keep in mind that if you plan to scale an image at all, you must set the resizeQuality of the image to "good" to keep any quality in the image, which will slow things down more (the "best" setting will be unusable). AcceleratedRendering helps here, but I think the speed enhancements provided by this property are achieved by a kind of buffering or caching of the region that is "in motion" so trying to scale things while that is happening will likely slow things down. With the above said, if your effect is going to take place in a region of a card, instead of full screen, you might get decent performance. My *untested* opinion is that getting an actual Ken Burns effect natively in LC is going to be difficult, if not impossible. It would be great to see someone pull this off. But to accomplish the actual slow/smooth 60fps motion of the effect, I think you'd be better off using a browser object along with a jquery/Javascript slider to move your images around -- there are dozens of libraries/plugins out there. Even with these, the effect can be very processor intensive. I recently rebuilt my own web site that has a Ken Burns style image viewer for the opening, and if this stays on the screen long enough, the fan on my system kicks in.
