There is a thriving business in the USA converting Tesla UMC portable charging cables into J1772. Just chop off the plug and attach a J1772 plug.
I am in Australia and now have a Model S. Tesla use the Mennekes plug which supports three phase 230/240/250 volt power that is reasonably common here. It also supports single phase charging. I have made a J1772 to Mennekes adaptor that works perfectly. I can suck 240 volts at 32 amps from public charging stations which is handy for holiday trips to places where that infrastructure has been supplied by local government. I have heard via the local EV association mailing list that several people have made the opposite to allow charging of Leafs and iMievs from Tesla destination chargers. Given the electricity is supplied by the venues and there are only 800 Teslas in Australia this doesn't seem unreasonable. You need to read through a fair bit of misinformation and irrelevant bumf but eventually you get to the bloke at the end who has done it. http://forums.aeva.asn.au/forums/tesla-hpwc-adaptor-j1772_topic4834.html This is in Australia but I can't see why Tesla would design multiple boards for the wall adaptors if they didn't need to.
