About adding the second cap:
For other reasons - maybe, but for safety...
When you use a voltage 2:1 divider, its impedance as the signal source at the centerpoibt is half of that of the single cap.
So 0.01uF cap lets through 0.45mA max current at 120V.
The two to one divider of two 0.01uF caps will lower the voltage to 60V. But it will still let 0.45mA max current.
PS. Neither one is dangerous.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
