Just move R22 etc to the other end of R21 etc, on the base of the PNPs. Where they are now, those resistors are are doing nothing but wasting power. When the NPNs turn on they're going to draw 1.6mA and drop 160V across the 100k resistors R21 etc. You need no more than 3V to turn on the PNPs, so in theory you could drop the values of R22 etc to 2.2k, but I suggest 10k is more suitable. 100k is way too high and may as well not be there.
