I think if you were devoted to such a path it might work to create a new life for you, but it probably depends on the individual and the circumstances of why they wish to die.
I considered options such as this, and living out in the wilds somewhere, but I realized that I'm in pain just existing in this state and just being somewhere else wouldn't solve it. It needs to end.
If you're going to CTB anyway might as well give it a try if you think it'll help, but like the rest of life I doubt the path will be easy.
