I have put on multiple stage shows and I... hmmm this is hard for me but let me just say this, most likely, you have all the parts necessary. The trick is presentation. You can take something so simplistic and you can use it as a pillar for so many effects as long as you present it differently. Here's an example. In high school I went to school with another magician I am close friends with, at the time we weren't but there was a talent show, this was the second and I had won the first the previous year. I tried to do magic that was innovative in the eyes of the PERFORMER and though it was, and it was more complicated, the audience would never know this. My magic also was not catered to my audience as well, they wanted quick visual eye-candy, they didn't care that there was something *deeper* more meaningful going on and all that work I'd put into performance theory to create one on one experiences that transported people through some kind of journey and left them with catharsis was for naught on the stage, I really hadn't thought it through.
The other magician did effects that all used a riffle force and wow'd the audience because the revelations were all so different in nature and seemed monumental, this erked me because I was doing more advanced things but he was doing better with simply a riffle force.
Nick (the other magician) and I later became really good friends and the following year I decided to set up a benefit for the humane society and only had a week to do so, I of course asked nick to partner with me. We had a week and we adapted all of our one-on-one magic for the stage. Again, these effects looked completely different to the audience members who had seen the same basic trick before, but it looked completely new. I did this by mixing effects together to involve more audience members, and patter, showmanship, subjects such as "creating a mental link" remember lie lie lie lie lie but be believable. You have to believe in what you are doing. I know I'm being vague, I'm debating how much detail I'm going to give out because I've been working on another show for so long but, PM me or something and we can talk in more detail. I'm curious about what you're going for and I hope this helped spark some ideas. Also, check out Get Neiman. I haven't seen it myself but i hear it has great stuff in it. Anyways, I hope this was helpful
