Thought that I'd post an update on this.
After living with it for a few days, I am more than a little happy with it.
It has breathed new life into my S3. The function of the select buttons remains the same but previously, I found that while I did use them, I subconsciously avoided using them often because having to carefully press those little keys distracted my attention. I haven't heard back from anyone about wanting a unit made and to be honest, it is quite expensive to have a prototype made up so I'm probably going to live with the guitar pick hack for now. It works really well. The key is to use very thick picks, I have a variety on there now as I was testing different ones. The dunlop 207 (see attached) seems to be about perfect.
A note, it's critical to make sure that you cut slots in the tape where it covers the fader slots, if they faders are even slightly impeded, they will not function.
