Yes, I suppose one should probably use a bit stiffer divider than I
suggested.  With the resistors I suggested, the gate voltages would be only
about 90% of the target feeding a 100-k input impedance.  However, I don't
like to overdo current shunts -- I don't want to have to buy another power
supply for another couple of cabinets at least!
