I'm not sure I'd go even that big. The original was twice that
resolution and had a lot less JPEG artifacting.

Actually... you might be going about this all wrong. If you really want
to use this to produce a very large physical print, I would consider
embracing that the original image is smudgy by upsampling it (maybe to
7200x3600 if not 14400x7200 after cropping it to 2:1) and then applying
some of gimp's artistic filters to achieve a look that is more
"painting" than "photograph". This will make some of the lack of
quality in the original irrelevant. At least give it a try digitally; if
you don't like the result, all you've lost is some time.

Also, make sure you save the result at least as a JPEG with 98% to 100%
quality, if not PNG.
