Thanks for the help guys.

Hans, thanks for the suggestion. Unfortunately the wmf export gave some really ugly results.

Erik, thanks for the help. So exporting to svg from pdf also isn't an option? Too bad.
I've also tried Xtreme's SVG export, but everything was exported as bitmap - even simple objects
I think I'm on a lead now. If I select everything and ungroup them, convert them to editable shapes, then the result looks like a step in the right direction. Maybe something will come out of this
