Immersive Dress up opportunities

I have been to Vegas dozens of times and I love everything this city has to offer. I've seen the shows, eaten the food, and marveled at performances. Now I want a personal piece of the action. I am looking for venues that offer immersive/ makeover experiences. I see show girls, can I be one? I see knights in battle, can I have a turn with the sword? Does vintage Vegas have any steps back in time to experience that Classic Vegas glitz and glam? Can someone teach me to soar like a circe de solie performer? This can range from glamorous to goblin. A full experience to something as simple as a photo opt. I'd love to experience Vegas not just observe it.
