This is a poor idea. Increasing mass decreases your ability to keep
something steady because you're correcting for more when there is a
disturbance which means muscles have to work harder (leading to fatigue
and less ability to control).

(Trying to shoot freehand with a 300 f/2.8, for example, teaches you
this quite quickly).

Adding mass for stability only works (typically) when the mass is
attached to the ground, or when it is a resonant tuned system and the
mass is carefully calculated (or experimented with) to find the right mass.
