Hiya!
I’d love to see that as well. Google Docs doesn’t have a native downloadable file format to directly translate to, so it’d have to be some backend alchemy to make .pap files into Google Docs, then back again, without losing the essence of a Papyrus file, like our precious Text Styles and document statistics. 
What’s your current workflow with Google Docs? You can export your manuscript as a .docx from Papyrus, then open that .docx in Google Docs from your Google Drive, for example.
I just tried it out, and while some things ( like those text styles!
) don’t translate perfectly, the collaboration features like comments, deletions, and insertions do make the round trip from Google Docs.
Here’s what it looks like, starting from Papyrus, to Google Docs, then back to Papyrus, saving as .docx between stops:
In the picture, there’s a comment, some deleted text, and some inserted text while Track Changes was on in Papyrus. They’re all shown in Docs. 
And then the same after inserting, deleting, and commenting in Google Docs’ Suggesting mode, and bringing that .docx back into Papyrus:
If your collaborators use Suggesting mode when leaving insertions/deletions, those changes should carry over into Papyrus with the .docx.
When exporting to .docx, you can remove some of the Papyrus special sauce, like scene/chapter icons and Ghost Text, by going through the checkboxes in the export dialog.
These checkboxes are for what you want to delete, not what to keep.
