Noup, unfortunately not via any kind of API. The only thing that MIGHT be possible to somehow synchronize the files in the vCO installation folder (under ..:\Program Files\VMware\Infrastructure\Orchestrator\app-server\server\vmo if you are on windows, /opt/vmo/app-server/...... on the appliance)
There is the folder conf with all the configuration settings, and the plugins folder containing the .dar files with the plugins.
Be aware that most of the newer plugin (like SOAP/REST/Powershel...) keep their configuration (a.k.a. connected hosts/endpoints) within Resource Elements inside the vCO database. These can be automated within workflows (Server.createResourceElement() and the ResourceElement and ... category types).
Resource Elements are also exposed via vCO's REST API.
Good luck! :-)
Cheers,
