Actually there might not be anything special you have to do any more. It used to be that you had to make new shapekeys and have them in the right order for blinking to work because it just used the top 4 regardless of what they were. Now you can actually assign a shapekey for blink. I don't know if unity will cap out at 100 strength for a single shapekey. If your gesture's shapekey is the same as your blink it should be fine, right?
