Beware.. The static current drain is 0 into the gates, but you still
have to charge the gate capacitance.
You might end up with significant glitches when you switch them on,
especially if they all go at once.
Figure it like a resistive divider, Cin/(Cg1+Cg2....)

Series resistors into the gates will help, if you can deal with the
slowdown in switching.
