Difference Clouds duplicated in Xara Xtreme?

[HayTay]

I'm still on my quest of learning how to duplicate certain Photoshop effects using Xara Xtreme. So far I've been more than pleased with the effects I've been able to achieve. Right now, though, I'm stumped on how to recreate 'Difference Clouds' raster effect using Xtreme with or without an Xtreme compatible filter or plug-in. You can see the effect I'm trying to achieve here: Filter>Render>Difference Clouds Example.

Fiddling with Fractal Clouds fills doesn't seem to have the same result. Also, I've been unsuccessful in my web and TG searches for a plug-in, and the plug-ins I have installed don't seem to be able to do the trick.

Any tips or suggestions for XX would be greatly appreciated,
