Very new, in fact. And I can say with surety that I don't really like the implication that we might become like them. Humanity is unique in its capacity to understand all facets of life, and I'd rather not risk losing that for any form of divinity. The eternal life I strive for is more metaphorical.

Only The Seven currently, those that won the Archon War and were allowed to lay claim to an element and a land to govern as they saw fit. Though it hasn't always been the same individual. Fontaine, for example, had a previous Hydro Archon before the current one. As for what I would do? Well, it's their job to interfere when danger presents itself, protecting their people from harm. So unless something is keeping them from doing so they would already be aware of the issue and actively taking steps to intervene, whatever form that might take. I wouldn't need to beseech Lesser Lord Kusanali for a matter such as this.
