Since I was only assuming, and approximating that distance to be
sometime near conjunction, not actually 'at' conjunction, then I'm still
free and clear! ;0P

Yup. This is something I've been yapping about for the longest time. The
problem with current space propulsion is its dependency on mass. We need
LOOPHOLES people!
Now, given the estimate of two weeks with that americium drive, such a
drive would only offer a maximum of a fraction of a g acceleration.
Frankly I like Zubrin's uranium salt water fission drive concept better.
