No, the gate drivers would be overkill as they add isolation and power switches.
The Skypers need 0/15V drive signals while the main board provides only 3.3V. So you will need to do some level shifting either with an IC (don't know which one) or some simple PNP transistors. Emitter to 15V (you have to generate 15V anyway for powering the drivers), base to main board via 10k resistor, collector to skyper input with 1k pull-down resistor.
