(SVG) Graphics in keycap legends

[looselyrigorous]

Hello,

I have in the past printed keycaps that have SVG graphics in their legends using KeyV2, as shown in the picture below. I'd like to accomplish the same using this project but I can't say I'm entirely sure how to go about it (I am a complete novice in OpenSCAD). Some input, or hopefully, a new feature to add this functionality would be greatly appreciated!
