What happens to AE comps once a Team Project is converted to a Premiere Pro project?

Our workflow consists of dozens of AE comps for titles and text builds across many Premiere sequences. We're considering using team projects, but I need to know if the AE comps will be accessible and editable once we convert the team project back to a Premiere Pro project for local archiving. Additionally, once the programs are completed, we produce foreign language versions of all the titles and text builds. Historically we've used dynamic linking to achieve this by duplicating the project files to create the alternate language versions while maintaining all of the linked paths of the English version.

In my testing so far, when the team project is converted the AE comps still appear on the timeline but cannot be opened. Additionally, AE elements such as adjustment layers and solids show as missing when the project opens.

I'm looking for more information on this workflow before committing to the Team Project approach.
