How to add OEM CAN drivers in exiting CubeMx_ARMMDK project?

Hi,

Does any one know that how to add OEM CANopen driver in to existing CubeMx+ARMMDK project.

History:

I have started project by using CubeMx to configure required pins and peripherals. It is working ok. Even I have configured required CAN pins using CubeMx.  CubeMx is does generate HAL CAN related code. Now we have decided to use OEM CAN library. So do I have to remove MX_CANx_Ini   call and use OEM CAN driver initiation code?

Has any one tried to mix HAL and OEM driver code in one project ​?

If so then what should I take care of.
