Has anyone upgraded a PREMIUM with a small 3kW and kept all or most of the glove compartment? That could be a pretty decent combination.
I think every single level 2 station in the street is 11kW. My homecharger is also 11 kW so 9kW is surely worth it.
here's a link to the installation manual of the chargetank for the SR/F SR/S for the north american market (with J1772 plug)

So IF the 230Vac connectors of the 3 kW charger and the 6 kwcharger are the same then that part would be easy (just clip it in)
The battery connection (DC side) would be more involved because i don't think the connector to the back of the battery and the connector to the charger are not separately available. You COULD try to tie it in with the existing cabling from the 2 chargers but adding 50% current to cabling that is desinged for 2x3KW DC does not sound very smart
And then you would have to shorten the "bucket" so it fits on top of the third 3kW charger.
I think it is doable but involved.
The connector that is present in the harness for the 230Vac to the additional charger is an Amphenol radsok A.
In this thread there is more info about it.
