You could but the device layout would stay the same as the Tilt2. It would be easier to use a Verizon keyboard layout cab on the Tilt2 if you are already familiar with the VZW keyboard.

The keyboard layout is a device map, so if you use a different device-map setting you get a different keyboard layout. Only issue is that the keys will no longer match what the physical layout is. Which is a non-issue if you have the Verizon keyboard layout memorized other wise you may want to take a picture of the Verizon keyboard and use it as a refrence from time to time while using the Verizon keyboard map on a Tilt2.

Hope that helps.
