Hi Lokki,
Great that you are getting around to experimenting with the Trill sensors. Using two Trill crafts to make a complex interface with 60 channels will work a treat. Here's a photo of an instrument I built using two Trill Crafts and pieces of brass. Each brass piece acts as a capacitive sensor with a variable reading.
You get a variable reading for each sensor channel so yes you can read something which is approximately equatable to pressure although as Giulio mentioned it is more a reading of how much contact is made with the capacitive surface rather a reading of the pressure applied.
In terms of sensing the direction of finger movement you will need to think about the best layout for this and interpolate between multiple channels. If you have a look at the other Trill touch sensors you will see the kind of layouts we have used to make sure that a fingertip is always touching more than one capacitive pads at once (the zigzag shapes on the sensor surface). This allows us to calculate the position of the fingertip. You can definitely achieve similar effects with two or more pads close to each other or interlocked together. It's a lot of fun to experiment with as geometry plays a huge role in deciding the effectiveness of the sensing.
