So I didn't actually have to use IK, but rather made a target bone that behaves like an IK target for the path. This is the best I've been able to come up with - a path, one stretched bone constrained to the path (set to chainscale), and the path is weighted to an anchor bone on one end, and a target bone on the other.

So I want it to both rotate toward the IK target bone, and to scale relative to how far away the IK target moves. However, I'm looking for a way to stretch a bone toward an IK target without the use of a path. I know it's possible to use an IK target to stretch a path, and this path can be used to stretch bones within it set to ChainScale.
