Hi,
which NXP board do you refer to?
MPC574xPEVB has 2 CAN interfaces so there should be no issue to use it.
DEVKIT-MPC5744P offers single CAN interface (SBC's CAN transceiver on revE or standalone CAN transceiver on previous board's revs). Thus other CAN transceiver must be connected FRMD+ headers.
DEVKIT-MPC5744P allows connecting of DEVKIT-COMM board, so you can expand CAN or LIN interface easily.
Not sure of MBDT setting, but you can ask this on https://community.nxp.com/t5/NXP-Model-Based-Design-Tools/bd-p/mbdt
