Hi Josh,
generally yes. However the WorldJetway jetways are usually not designed to lower that much to the ground (the CRJ door is pretty low). That's probably why they don't work. You could try it with a parking position far outside on a long extended jetway.
In worst case you could manipulate the WorldJetway values to lower it but that causes visual glitches so I will only describe you that if you really like to know it
