Sure, but the interaction between the agenda system and the normal relationship modifiers leaves a lot to be desired. If he has two neighbours, both nearby, both east to conquer, the agenda system doesn't lead him to prefer attacking one over the other unless one of them happens to have the most (or the least) mountains. So he could have one plains-based neighbour along the coast and a second neighbour whose territory consists of almost nothing but mountains, but if on the other side of the world, far away, there's some other civ with 1 more mountain, Pachacuti's agenda doesn't lead him to covet attacking his mountain neighbour over his flat-lands neighbour.
