It works in principle, but it's a very big engineering task, and an enormous expense to boot. To avoid noticeably different acceleration between head and foot,* it's going to have to be substantially larger than any spacecraft we've ever built, and the biggest spacecraft we've ever built cost over $100bn. It's also going to have to withstand stresses larger than anything we've done before.
There's no reason to doubt we could do it, but it's a very big step from where we are now.
* And if we don't do that, then we stray into the realm of untested biological issues. We have no idea if people can live safely and comfortably like that.
