This could work, but I see it more as short skits on the internet like on a YouTube channel. There's a lot of people that do things like that nowadays with high looking productions, and it's not difficult to make. If it were a tv show, a group of different skits all put together (field service, elders meeting, family worship, etc.), or a mockumentaday style filmed like Modern Family or the Office would do. I'd make it the characters a JW family with the dad as an elder and have a comedic family friend from the congregation. Then they could come across different experiences that would be made funny, like one of the kids explaining how he had to resist the delicious looking birthday day cake at school, or how another kid competes with the family friend on who will place the most Assembly invitations at field service. Then you can see them stuffing the invitations in people's mailboxes and running door to door. I'm liking this idea.
