Reasonable possibility, but doesn't that make the transformers and hookup to the grid the gating factor? Some superchargers have waited for months for a transformer. Can they even be manufactured fast enough?
And site selection and permitting seems to be really slow and somewhat out of Tesla's hands when it comes to speeding it up much.
Any streamlining of the process is bound to help. If the transformer is a problem, then don't install the Superchargers until the day after the transformer is in place. True, they can't speed up the utility's process, but they also don't have to suffer as a result of it by having spent a month doing installation, then having the whole thing sit there for another month, waiting.
A permit to put in a commercial air conditioning system is much less complex than one for constructing a building. If, in SOME locations, if putting in the pre-fab Supercharger is able to be done under a mechanical permit rather than a building permit, the process might be quicker.
Also, as an aside -- asking for suggestions will be better received if it isn't just a skeet shoot for you to blow holes in the idea. Nobody will throw plates up for you anymore.
