That sounds like a good question, if it's true that Martin became the new Stone there. I honestly dont' see why not; all you'd have to be, I think, is a Tonal Architect.
But at the same time, Lorkhan's Heart, the First Stone, was the Heart of the World, so that could be a special case, as Lorkhan himself is. I personally think not, but just on base knowledge and not lore, yet.
I dont' think you can literally bind yourself to an Earth Bone; I'm positive that they are the "intangible" laws of nature.
