Melt some bird shot, fishing weights, wheel weights, or dive weights in a dollar store pot on a camp stove, propane grill, or with a blowtorch, and slowly pour it in. Probably want to remove the harness for this, and wear appropriate protective gear.
Or just buy the XS pouch, a weighted STA, or one of the nice DSS weighted plates.
