I'd like to create a visualisation that uses many pngs with transparency. I would be up for creating the pngs and coding the thing. But I was wondering if it would be too demanding for xbmc to display around 5-10 pngs at a time

I dont know for sure but i dont think it should be an issue. the "vortex" visuals use pngs and bmps in its display. theres one with a scull and crossbones repeated many times on screen and it runs fine.
hope this helps.
P.S. not sure if the "vortex" visuals are available on all platforms but its definitely there on the xbox and if the xbox can handle them, i have no doubt other platforms can handle them as well.

Well basically all I want to do is to display randoms pngs across the screen and make them move in a direction.

this will work just fine. bind the png's to a texture and it will reside on the gpu memory. even the xbmc gui displays 20-30 images at any time..

Just a few things to keep in mind.
Keep the images in a "sane" size. For example 10 15MPixel textures will cause a problem on some graphics cards.
The other thing is how large you want to display them. Converting the screen completely with 10 alpha blended textures on a 1920x1080 screen will bog down most graphics cards.
But try anyway even if that was your plan. You will learn in the process and you can be quite sure you will find an effect that do work even if it wasn't exactly what you intended with from the start.
