Company Rebranding - Remove watermark in batches.

Good evening, 

I am an owner of a Real Estate company. We are rebranding, but we have a significant issue with the photos. All of our images have a centred watermark. We don't have any originals; our current website automatically places the logo when the listing is verified. 

Is there a way to upload the original watermark on Photoshop and create an action to remove it in batches? The opacity of the logo is 40%. I want to remove it from the images and not fill it with the content-aware tool since the background behind the pictures shows.

This will make sure that the images are not touched, as property photos are quite complex, and we need them to show as they initially are. 

I really appreciate any help you can provide.

Regards, 

Leanne
