Would it work? Well, just like the Morgan interview and its wider impact, that's something which is difficult to pre-judge from the confines of Westminster. Of course, dealing with anger about job losses and troop deaths is in a whole different ballpark to a televised conversation with a Designated Prime Ministerial Friend - especially when there'll be more bad news between now and the election. But you imagine Downing St hopes that the Brown-as-Human onslaught of the past few weeks will take some of the edge off that.
Myself, I suspect the risks of it all will put Brown, and his aides, off. This is not, after all, a man who's known for mixing it with the public. But if there's one hard-and-fast rule about politics, especially after the past few weeks, it's that you never, really, can tell.
