According to the guy that I've talked to, the US bumpers are bigger than the Mondeo's, so I'm going to guess no. However, anything can fit with a sawzall and duct tape.
I'm sure that with few mod's though that the headlamps or bumper cover's could to be made to fit, that is if both are roughly close in width and all. It's something I've been considering for awhile but have yet to do.
