Autoexposure works fine with a little bit of care. It's how I take all of my panorama. Shoot raw. Take brackets if the intra-frame contrast is too high to capture in a single exposure. Develop the raw files, cranking highlight recovery to max if needed, plus shadow boost. Assemble 16 bit tiffs

The main issue is the deliberate parallax for stereoscopic imaging. You will only be able to get good alignment if your control points are on objects as far away from the camera position. In principle, you will only need 2 pairs of control points to align 2 panoramas with y, p, r adjustment.

What you can do is custom optimise and choose what parameters you want to keep fixed on the optimise tab that comes up. Make sure the parameters for the 1st panorama are fixed (unticked) and that the lens parameters are also unticked. Then just optimise the y, p, r parameters of the 2nd image.
