Thanks, Doug. I rather like the Idea of an extra wheel set that can go on and off with little or no requirement for further alterations. I am not concerned about rear brake failure since the principle purpose of this brake would be to act as a backup to th front brake. I am more concerned about any additional drag caused by the coaster brake mechanism.
Now that I think about it, perhaps that new SA kickback hub would suffice...
