Julio,
There is no easy way to add a component to a post-FBA image. You will need to go through the component resources (registry, files,
dependencies, registrations, etc.). Then you can package the collected info in to a DUA package (if you got DUA in your image) or
deploy the files and registry entries some other way depending on your access to the deployed devices.
From experience, usually it is a headache to deploy a component to a post-FBA image even if you have got DUA in the image.
Easiest way sometimes would be rebuilding the image and re-deploying it to all the devices in the field.
