LibreCAD 3 was always intended to be pluggable so this is for sure possible.
LibreCAD 3 has an separate 'kernel', 'renderer' and a batch based pipeline to make modifications on geometry.

Each entity can also hold any meta data so vertexes from one application can be matched with vertexes from a other application by a simple id. Cairo was always ment to be the reference implementation so you could even render 'offline' into a PNG and draw that back into a other application. Or just use the render engine and plugin your own graphics API...

Source: I started LibreCAD 3... But some great people are nowdays working on it!!!
Note: The original LibreCAD (the qcad fork) was not suitable for this...
