I'd import all the images into a single project. Image align stack each set of
exposure. Stitch together one image from each exposure stack into a panorama
(e.g. the middle exposures). Thus the others in the stack will also be aligned.
Then I would export each exposure separately (light, mid, and dark), finally
enfusing them. This is my usual procedure for doing exposure fused panos, e.g.

Interesting - I do the exact opposite, due to performance limitations on my
box. The FIRST
thing I do (using a small perl script) is identify each bracketed set and
enfuse them
from the command line.
From then on, it's just (from Hugin's POV) a simple pano.
This gives a minimum RAM usage - initial enfuse is small, and final stitch
is smaller.
If you do it stitch-then-fuse, the final enfuse is very RAM hungry; it's
effectively
ALL the source images handled simultaneously.
In theory, the low-RAM method could lead to edge effects, since the enfuse is
being
done without global knowledge, but in practice, decent amounts
of overlap (needed for good alignment and stitching in any case)
render this problem vanishingly small.
