I just pushed some cpfind improvements (improved rotational invariance, through new algorithms and parameter tuning), which should result in much better performance on fisheye images. The above image set now stitches with default parameter when using the assistant. I want to perform some more tests, and then close this issue.

After some more parameter tuning, the latest cpfind seems to work quite nicely on projects with fisheye images, too. I tried several projects, and except for some hard handheld ones with little overlap, the assistant stitched them quite nicely.
