I think the radiation protection is fairly trivial there's just been no need for us to ever worry about it. Storing water evenly around the hull in something like an inflatable bladder would provide some impressive shielding, in the emergency of solar flares there could be a cramped secondary space with greater protection where the crew can wait it out.
Another cool feature of storing the water on the outside would be micrometeorite protection.Instead of creating an airleak the exposed hole would freeze over and self seal. This also reduces the need for protective baffles like on the ISS.

For gravity it really depends on how big you make the ship, the spinning tether idea probably has the most merit over building a fuckoff big ship. You probably don't need a full 1G either which further lowers the constraints. They really are going to have to do more work understanding the biological effects of 0.3-0.7 G. I don't understand why they haven't been doing small spinning experiments with mice for a few months. Surely they're able to sustain them for a bit in orbit?
