I have some Saucony Kinvara which are 0mm drop and from their "Natural" range so not quite barefoot but saw those a few days ago and fancied trying them for softer off road running.
As in on softer surfaces? I guess they could work, but you'll feel every rock and sprig under your feet. And they're not even remotely waterproof, I wear them sockless because I prefer my feet to get wet directly instead having wet socks.
