simply longer stalks may be too simple
The extenders give somewhat independent control of the fore/aft mirror position and the mirror separation. This would not happen with longer stalks, which would necessarily couple those variables.
At first glance, you might think separation is fine as long as it suffices to clear your shoulders from the view seen in your mirrors. I found this not to be true at night, when keeping headlight glare from the vehicles behind me matters. Then, I like having to move my head slightly to be able to see directly behind me, in the same lane. That means there is a head position which keeps that glare from degrading my forward vision.
