The electrical engineer moved the lights, and now every single diffuser has to shift 3 feet. How do I manage the rework efficiently?

Do not dismantle your entire main rigid duct trunk line infrastructure. Disconnect the short final branch connections or spin-in collars leading to the affected diffusers. If the modification drops within code length rules, extend or loop a code-compliant length of insulated flexible air duct over to the new acoustic ceiling tile lighting positions. If hard pipe is required, fabricate a standard short-radius rectangular transition offset to shift the drop drops over cleanly.
