Different Post-Production System

Hello
I have a completely different question:
I can perfectly capture 1080 footage with the ATEM ISO, edit it with DaVinci Resolve (on a low-end computer), and at the end of the post-processing process, I replace the ISO file with the 6K version and have it rendered on a high-end computer.
Now I have the task of recording 6K videos for a client with a low-end computer. He works with Mac and another editing program.
I want to send him the small ISO files in 1080, and he should edit and reassemble them.
I then want to import his MP4 files into DaVinci Resolve on my high-end computer, and based on the timecode in the MP4 files, and DaVinci Resolve should overlay my 6K RAW videos for Rendering.
Is that possible?
