Replace background of two family group photos

I need someone skilled with photoshop/ai prompts to replace the background of two family group photographs taken against a church during a wedding. Both uploaded as samples, can provide RAW, TIFF, high res jpeg later.

The church doors were left open, leaving the entrance hall and notice board showing. Both images need to show shut doors, mimicking the style of door, tone of wood, decorative metal gate that you can just about still see on the images.

The work obviously needs to appear as genuine as possible, and not prompt anyone to notice. There will likely need to be a bit of manual cloning of the new background between the bride and groom.

Need doing in the next few days.
