Hi, Craig!
Someone sent me the BigTIFF executor to generate BigTIFF files. Here it is:
[General]
Description=Normal panorama, BigTIFF
StepCount=2
IntermediateImageType=tif
[Step0]
Description=Remapping images
Type=remap
Arguments=--bigtiff -v -r ldr -m TIFF
[Step1]
Description=Updating metadata
Type=exiftool
Result=%prefix%.tif
Arguments=-overwrite_original -TagsFromFile %image0% -ImageDescription
-Make -Model -Artist -WhitePoint -Copyright -GPS:all -DateTimeOriginal
-CreateDate -UserComment -ColorSpace -OwnerName -SerialNumber %result%
Copy paste that into a text file called bigtiff.executor. Put that file
into the ~/.local/share/hugin folder. Sorry, I only use Linux, so I
don't know where it belongs on Windows. MacOS is probably similar to
Linux, but I don't know that, either. I suppose other folk on the list
know those platforms.
To use it on a particular panorama project, open the project in Hugin.
To run the executor from the main Hugin GUI, simply load the executor
file using the Output menu option and select the "User defined
output..." item.
Note: My Linux set up has BigTIFF support. I don't know what happens on
systems without BigTIFF support; I'd guess an error message?

I read about bigtiff but at least on the GUI there was no way to turn
it on and when I tried entering the switch in the output parameters it
threw an error and would not output anything at all. I tried 2-3 times
and after 30-40 minutes stitching/blending it would throw the error
and terminate. Maybe I missed something on how one would enable it?

Re TIF format and big file sizes...I've found out (thanks to folk
on this list) that Hugin supports BigTIFF format. That can handle
enormous file sizes, such as 1 terapixel. You might try that.

So in the end I had issues exporting the files from Hugin with
respect to file size limits (1.24GP at 16 bit did not play
nicely with TIF format.)
I switched to AutoPano Giga because it has the ability to
export a PSB file with all the layers included as aligned. In
the end it was quite obvious that several of my source photos
were faulty and both Hugin and APG did a decent job blending
them as much as possible without seams. In the end I manually
finished the panorama with manual blending and color/tone
correction on the manually blended areas using the exported
panorama as a skeleton.
Between the two I would say that Hugin is more powerful and
definitely easier to edit the control points, but APG is more
capable when it comes to export formats and generates CPs
faster and more accurately, but it is much slower for
previewing the aligned panorama. I'll be keeping both because
I see each having a valid role and either will perform well
when it comes to a panorama shot without as much shifting as I
imparted in mine.

Indeed, the left side is also worse than the right side, I
had missed
that. Then the cropping should be asymmetric of course,
unless the
images can be improved.

I found your other non-pano Phacelia, very nice!

In my proof of concept the control points could have been
optimised
further, there was still room for improvement.
I gave the strategy of just fusing the images another try
because it
really should work. While hugin seems to refuse to put
non-overlapping
images into the same stack there is no such problem for
enfuse itself.
So, one can generate individual remapped + not-exposure
corrected images
from hugin and feed them into enfuse on the command line
and get the
intended output (enfuse image1.tif image2.tif -o out.tif).
I tried that
with a few different fusing options: entropy and contrast
do work but
the differences between 0.0 (off) and 1.0 (max) are only
visible in a
difference image. Soft-mask vs hard-mask are noticeably
different but
I'm undecided which is better (probably soft-mask which is
also the
default). There are plenty more options that I haven't
tried, but if
this is an approach that works well otherwise you could
spend some time
with that.
Hard-mask vs soft-mask:
http://78.46.190.157:8080/cistus_fused.tgz (1040mb).
I don't know if this is a better approach than what I
suggested
previously. Pure fusing fares better with blurry regions
while blending
does better with minor parallax and aligned issues -- so
it depends on
the input images.

It is always interesting to hear what finally worked!
