Is there any software out there that can look at 2 GEDCOM files and generate a third one that contains all the people who are NOT common to both?

One answer may begin . . . . .
The criteria you choose to match individuals (or not),
and the completeness of that data on each (person's) record on (each of) the gedcom files(tree).
[ To define who the person is ]
I can think of a piece of software, Gedxlate, (Search Rootschat for more detail)
which can generate separate files (in say, Excel format)
Ensure the files are in the correct comparison sequence.
Then run a compare.
Unless you can find a FamilyTree application to do similar.
Sounds complicated but really is not AND there is more than one way of "x?><(*&^"ing the cat.

For the moderately technical.
Gedcom files are just text files.
Take a copy and add a .txt extension and open it in a text editor. Cooy that into a spreadsheet and tinker.
-
try using Notepad++ with the compare plugin installed
https://notepad-plus-plus.org/download/v6.9.1.html
It is a free open source program and it will allow you to load the gedcom file without changing the suffix.
In theory it should work (and it does with smaller files) but larger gedcom files 1000 individuals + and it falls over :-X

I haven't used it, but I understand GENMatcher from Mudcreek Software would be able to do the comparison part. From looking at the manual, it appears you can set criteria for how closely records match, and there are various options for reporting either matches or non-matches. However, it only gives a report of what it's found, and you'd then have to use that in selecting individuals manually to create the new GEDCOM file.
It's a commercial product, but there's a limited trial version available - see http://www.mudcreeksoftware.com/
