It might, but you'll need something a little bigger than
a bulldozer to shove the Moon out of orbit.

In fact, you'll need two somethings, aimed at the moon
and hitting it at exactly the right times.  The concept
of a "free-travel transit orbit" is well known to NASA --
such are routinely done in order to get to other planets.
The general idea is to have an ellipse with perihelion
at Earth and aphelion at the target planet, if it's an
outer planet; aphelion is at Earth and perihelion at
one's destination if one is going to Venus or Mercury.
At the other end of the eclipse, the second burn ensues,
circularizing the orbit.

Since we don't have a rocket engine quite big enough to
do the job (the Moon is after all 73.5 quintillion metric
tonnes), we direct two little somethings from the Oort cloud
and hope for the best.

At least, such is my understanding of your proposal.
