Throw a Weight in the Back?

Anyone ever throw a weight in the back to get within allowable weight and
balance? I am flying a C182 with 430 pounds (pilot & passenger) in the
front row. The point is I would like both of us to sit up front for the
flight. I have other aircraft that I can fly, and this is not a required
flight (no safety flaming please).

Calculated arm is 37.99, and minimum arm at that weight is 38.15. I am
144.85 pounds UNDER gross weight at this point.

If I throw a 20 pound weight in the main baggage compartment the arm is 38.4
(meets the minimum requirements) and we can both sit up front.
