Spartan 3 CAN Bus connection to OBD2

Hi, Would it be possible to connect the can high and can low terminals of the Spartan 3 to an OBD2 socket in parallel with the existing vehicle can bus and see the Spartan 3 as a new module in the software along with the rest of the “normal” information?
I’m wanting to log the WB AFR against the NB AFR, rpm, fuel trims and ignition etc.
Thanks
