A nice idea, but unfortunately the lead is the problem: where do you
get enough lead to encase the fusion bomb?

I like this two-stage approach, maybe we should look at stars which
first brighten a bit, and then go nova...
OK, I have to admit that this scheme is a bit too conservative (in
the Drexler sense :-) for me, I dislike blowing things up since so
much can go wrong. So when I notice that you are starting to buy lead
and neon extraction equipment, several copies of me will be heading
for the stars as fast as their ships can go :-)
