Linux Mint Cinnamon is great and almost mimics Chrome OS

the pros of a fully operational OS are huge

Chrome OS lacks fully operational OS - therefore
a Chromium build (one that would default to the Chromium (Open Source) browser to mimic Chrome OS) would be a great benefit.

The second step would be to get this ISO to be able to install dual boot or overwrite existing chromebooks.

This would give Chromebook users a powerful OS

Would recommend using the WPS office instead, it much more Windows friendly. Also have some other default apps and tools on it pre-installed.

If it could integrate google docs and drive, even better.

The last step would be to partner with Chromebook vendors, to offer a mint version.
