Not right now. UBports (ex Ubuntu touch) would have to be ported to the Fairphone 3 first.
In terms of when it would be usable as a daily driver, if at all, then realistically think months or years, not days or weeks.
There are ways to achieve most of what you are after with Android, but there’s no guide yet on how to do it with the Fairphone 3, because almost nobody has a final production model at hand yet, and right at the start just now there’s no un-googled Android available like there is for the Fairphone 2.
I guess available info would then be added here …
