I think it's intriguing--lots of potential sonic exploration with that, in my opinion.
Travis, your post is fantastic--a real history lesson in a thimble. While I had heard of the Gizmotron in passing, I'll have to admit that I am not at all familiar with the Sustaniac/Fernandes-Hamer Sustainer. (I guess that means either:
1. I've been living under a rock and everyone else knows about the Sustainer; or
2. The Sustainer's manufacturer(s) didn't market it with conviction and/or could not find a high-visibility platform or effective integrated marketing channels to market it, so they lost interest in it because not a lot of players noticed it; as a result, the Sustainer has been relegated to the dim, cobwebbed attic of amplified music esoterica. I'll readily admit I'm going to feel really stupid if the former rather than the latter is true.

For years, I've been amazed that the
"E-Bow X six" concept has been, for all intents and purposes, all but ignored. If I had any kind of predilection toward and expertise in electronics, I can assure you that I would have been tackling this very concept. It looks like the Moog guitar "g(o)t thar fuhstest with th' mostest."
Interesting, to say the least!
