Apple Script Widget: more than two icons

Hi, I have several widgets that display my connected drives and servers (a bit like the AQT solution). The output is always

xxx GB free, YYY GB used

Now, I would like to display the Drives icon too. With a regrex I can only display one icon though (which is not enough), and the widget solution itself

"{"text":"newTitle", "icon_data": "base64_icon_data"}"

does not work with a variable to Display (the free/used space in my case).

Any ideas how to achieve this nevertheless?
My solution for now is to display these information w/o icon, and to have another widget that displays only the icon in base64, based on the name of the drive. But that's really hacky and not smooth, plus its another uselessly running widget.

Thx! Stay clear.
