About updating the project composition.

Hi all !!!

I need to organize the following process. After Effects composition has a Solid, which generates a black and white map. I need to transfer this map to the Illustrator application, make a trace, lay it out into layers, transfer the resulting file back to the After Effects application, open it as a "TraseBitmap" composition.
It is assumed that this process is often repeated during operation, so there is a desire to organize this process into a script, obtaining an image from AE, -->, -->.
It is assumed that such a map should be similar to the Smart Object from Photoshop, but for Illustrator. After executing the script, these compositions "TraseBitmap" are updated.

How to organize the update of the "TraseBitmap" composition in the form of a script, and in which format is it better to save a black and white map.
