EVGo has done it, but they've done it by using chademo adapters strapped to the side of the unit. Most of that was before Tesla added support for CCS signaling to the cars. Also, they did it in the most EVGo way possible. There was a high traffic route near me with no superchargers. EVGo had a location, but no adapter. But EVGo would put units like that in the same parking lot as supercharger. :facepalm More recently, a lot of manufacturers want to do it, but there's a different constraint. High quality cable and connector manufacturers are not yet making Tesla connectors in volume. Tesla doesn't sell their own cables and connectors to third parties. I'm hearing that this will all change by next year, though. At least one charger company (Freewire, IIRC) has committed to using them.
