This is a really interesting line of thinking, Andy. I'll probably try to give some time to my own judgement of 'your style' (because you deserve compliments!), but I think you could also take your present sense of alienation from your work as an opportunity. Lee probably has a great idea when he suggests that you create a work that forces you to make decisions and devise practically innovative solutions to your technical problems, rather than simply executing the technical process you perhaps feel has become stale for you. I don't think you'd necessarily need to go as far outside your norms as 10-Ball's snail rider, but there is absolutely no arguing with the stupendous results of that 'extreme' stylistic reach.
Take all this with a grain of salt- I'm looking up at you guys from a considerable distance (and you and the others you mentioned are a tremendous inspiration to me). Nevertheless, I suspect that answering the questions you're posing will prove a large step toward the artist you wish to be. I certainly look forward to your efforts, as well as your personal reflections upon them.
