Well, like a lockdown but slightly less restricted - like the "half way house" thing you mentioned.
I also hope it will work but its going to be impossible to tell before the whole pandemic is over. I also believe that it is going to cost a lot of lives now (could see us being very high in deaths per capita when we reach the expected drop in May/June) but save us a lot of lives in the very likely second wave of the pandemic and in the possible third.
I'm not sure anything 'works' better than anything else, isn't it just a case of quicker vs slower?
When 'the whole pandemic is over' has to be when a vaccine is widely available I'd have thought ... can't see how it's over before then, but more than happy to be corrected
