4-20 mA to Foundation Fieldbus

Is it possible to convert a two-wire loop-powered 4-20mA transmitter's signal to Foundation Fieldbus? I also have access to a HART/FF converter, and was wondering whether the 4-20mA signal without a digital signal superimposed on it can be converted by it? The transmitter in question is a GE oxy.IQ Panametrics Oxygen Transmitter, and it needs to interface to a Foundation Fieldbus system.
