I know they have different frequencies for different countries...
Your FCC approved US versions will work, however they will not be authorised and will not be approved for use like the correct CE versions would.
Potential problems are that the radio frequency can interfere with machine operations, safety switches, remote controls, emergency and police radio equipment, personal hearing devices and computer equipment. The US Pocket Wizard frequency is used by fire and rescue radios in Europe, so it wouldn't be a good idea to meddle with unauthorised wavelengths as you simply don't know what the result might be. What exactly is the wavelength used by the US RP's?
If the frequency does interfere with necessary legitimate radio controls, you could find yourself in big trouble, and if TSA or Border controls do their job properly and check your equipment, they could well be confiscated for not bearing a CE authorisation.
