In order to add anything to the output of an oembed provided by WP you would need to create filters on the output. This can be done using the embed_oembed_html and/or oembed_result hooks. Both of these hooks supply the HTML for the embed and you would need to parse the HTML and insert additional elements as needed.
If you can do that you could use a different ACF field to hold something to be inserted. However, there would not be much available in to the filter to allow you to match up the video being shown with any additional fields that you want to pull information from. You would need to somehow use the url of the video to find out what field that url was pulled from and then find the field that has your additional data.
