Can't contribute much, other than comment Riz, somewhere built a bespoke importer of JSON that bulk manipulated titles.
The specific use case was to have a way to import where you do NOT have unique titles in the imported JSON.
The code for that tool might be worth looking at. Maybe relevant. Let me know if you want me to find it for you.
On broader note anything that enhances JSON import/export is good news.
JSON is an absolutely perfect interchange & "database" format for TW.
Best wishes
