Creating a fun manipulated groupphoto

I need a funny picture of our scrum development team that I will use in a presentation. I have picture of each of the members, but that are in very poor quality. I want you to put our heads on a drawing, etc.., so it looks like a fun group photo. Some of the photos are in black and white so it's probably a good idea to create a black and white groupphoto. I'll have the presentation in a few hours, so the assignment must be completed within 6 hours.
