Help swapping heads from one image to another

I hope that this is the appropriate place to ask about this. I am a new user of Affinity Photo, but have used Adobe Photoshop Elements and an older version of Photoshop. I am working on digital art to help illustrate a fanfiction based on Stephen King’s IT. This is the base image I am working with:

I am going replace the heads in the image to be the characters in my story. I haven’t picked the image yet for the mother’s head, but here is what I am thinking of using for the kid cause the head looks like it is in a similar angle: https://i.imgur.com/wQHrJI4.jpg

Would it better for me to work with these images instead?

Is it possible for me to replace the stuffed animal with ether of these bears or a combo to fake the angle?
