i like the gist of both of your ideas but i'm not sure they are feasible for firefox, since both are expensive services (in different ways) that are a bit outside the competency and mission of firefox.
i could see firefox providing hooks for 3rd parties to make those services easier to integrate however (and maybe charging a fee, e.g., to certify the 3rd party). that would fall squarely in their wheelhouse.
That’s the point though, to take on something with real cost (and real value), occupy the Open Source segment of that market, and then grow that segment.
Netscape was trying way back when. Mozilla probably has some PTSD from those days so I don’t have high hopes.
Someone else will eventually come in and be Mozilla on the services side. Might as well be Mozilla.
