It can be done (with some difficulty). There is a small gap in the image
I produced though, since neither image covers that area.

* Split the input images in two. Save each half as a separate
image.
* Load the the two images in Hugin.
* Set their projection to circular fisheye. Use an initial field
of view of about 185 degrees.
* On the control points tab, place a few control points linking
matching features on both sides of the images. Pick features in
the distance as there is some paralax error (when you have
choice at all, since the overlap is so narrow). Hugin might try
to guess more accurate positions but I found it just made them
worse in this case, so I turned of auto fine-tune from the
bottom right of the tab. The more control points the better, but
they must all be positioned accurately.
* On the optimiser tab, optimise positions & view. Hugin then
finds a reasonable angle for the second image in relation to the
first, and a more likely field of view for the camera.
* On the crop tab, shrink the circle slightly for each image to
crop out the black outline of the image. Ignore the bit cut off
the side for now.
* On the Mask tab, remove the black bit cropped out from the sides
of the circle. Select an image, press add new mask, then click
to place the corners of a polygon that covers the black bits
that should be in the circle. Repeat for the other image.
* Use a preview window to check it looks OK. There will be some
error on the bits closest to the camera, and a hole on one side,
but the bits in the distance should line up.
* On the Stitcher tab, press calculate optimal size.
* Stitch or send to batch.

Attached. I named the images 00000001l.png for the left of 00000001.jpg
and 00000001r.png for the right.
