Wow, you've got a lot of great ideas there! I think you're on the right track by trying to differentiate yourself from the competition and offering a unique experience. The Denon Prime Go is definitely a great tool to have in your arsenal, and I love the idea of using a short throw projector to create a visual backdrop for your performances. I also think your setlist is a great niche to target the 40+ age group, and it's smart to focus on a specific demographic. One piece of advice I would offer is to make sure you have a solid demo reel or promotional video to showcase your act.
