Apparently it can be done as there is a lift kit available. Here's a link where somebody put one on there hybrid and also went with 14" tires as well:
Yes the hybrids do have lower ground clearance, but in the 2 years I've had my X23B, I've not had any issues with it. Some do if your driveway has a dip and on an incline, etc.
OOPPPS!!! Curtis you beat me to it, it was your link I listed!! LOL!
