Sounds great!
BUT PLEASE use standardized APIs and don't integrate "Microsoft style" with non-standardized interfaces, but with lots of bells and whistles!
Ideas like "for example, an ODT file can be viewed and edited directly in Thunderbird" sound a lot like MS-Teams. Pure horror!
AND ALSO für "consistent UI/UX ...unified settings"....PLEASE respect OS (theme) settings. Mozilla has ignored this more and more lately. Unfortunately!
Thanks!
