This might be a silly question but wouldn’t they adapt PureBrowser seeing as they already work on it for the laptop range?
To me, until convergence is working, I don’t see much of a need or desire to edit LO files on a 5.7" screen. However a viewer would be a nice to have.
In the absence of convergence, one approach for a viewer would be to convert the LO file to a PDF (automatically) and use a PDF viewer, seeing as a PDF viewer will probably be needed anyway.
Any viewer will probably be more lightweight than using a full-blown editor e.g. LibreOffice itself in the case of an LO file.
