There's absolutely people out there who can do it. I just see it, currently, as a two fold problem.
One, once it's been "scrapped" for a car, I don't know of any process in which it can be OK'd to put in a house with a mortgage and insurance. That's policy/paperwork stuff that theoretically can sorted if there were a push to do so. But, today, you're, right off the bat, limited to off-grid and DIY types at the moment.
Two, for those people, it's a lot more comfortable to work with a 48V system than 480V. You make a mistake with 48V, it hurts. You make a mistake with 480V and you're dead.
