But how do I determine which worlds are relevantly similar?
Obviously I have to admit some worlds where I have a million
dollars, but I also have to exclude all worlds where most
people have a million dollars. In other words, I have to
admit only those worlds where my having a million dollars
means I am rich. But then there is no content in the
expression, all the content is in the selection of relevant
worlds. Isn't it?

But this one fails even worse. Since I don't have a million
dollars, "If I had a million dollars then I might buy Microsoft
from Bill" is true, according to your expansion, because
indeed in some worlds relevantly similar to this one
(in all of those in which I don't have a million dollars
in fact, including this one) "If I have a million dollars
then I am able to buy Microsoft" is true.

You have to restrict it to worlds where I do have a million
dollars. Then you are just saying: "In some worlds where
I have a million dollars, I am able retire."

If "I insist that he go" is something like "mi minde fi le du'u
ko'a klama" then the truth value of "ko'a klama" doesn't really
enter into it, does it?
