Here is an article from Encyclopedia Astronautica which covers some of the later development work along with a NASA report on various types of space vehicles including the MOOSE orbital parachute system,

The configuration for that is slightly different from what's in the patent, but you have to remember that is the original 67 idea (Which I agree would need fleshing out.)

I'm not clear about some of the reentry procedure, the patent states that the sphere is under very low absolute pressure and is obviously not rigid, the returning astronaut will know it's safe to depart the "vehicle" once the sphere starts to collapse under the higher outside pressure of Earth's atmosphere. But reentry itself will result in fairly high pressures at times and you would want to maintain the sphere shape (for the frontal surface area as well as > 0.47 drag coefficient). A collapsing sphere centered around a mass will end up in more of a tadpole shape, which will have much lower frontal cross section and much lower drag coefficient which may result in inadequate deceleration. 

I think the idea is fundamentally workable, of course, I just wonder how much they fleshed out the details. 

I wonder when "personal reentry kits" will appear on store.spacex.com

Good ol' MOOSE.
