Car specific protocol to OBDII protocol bidirectional translator

[Gendov]

There are cars produced for countries where OBDII is not mandatory. It is difficult to register such car when it is imported in some country where OBDII is mandatory. My Infiniti FX35 2012 year has such problem. Because gas analyzers cannot read car data for measuring of emissions. Is it possible to make arduino based protocol translator from specific Consult III Nissan protocol to OBDII standard protocol? The translator should receive OBDII commands from gas analyzer (or other OBDII based device) translate them to Consult III commands and give them to the car. Then the provided by the car data should be translated to OBDII data format and given to the gas analyzer. I see there is Consult library but it is intended to Nissan port . I have OBDII port on my car but it does not support OBDII protocols. Only Consult protocols. Will that Consult library work on OBD port instead on Nissan port?
I see there is also OBDII library but I need it to work on reverse receives commands and provide data instead to give commands and receive data.
