    Are you trying to expose the virtual network adapters to the world (i.e. internet)?

    Yes, it is possible when you use virtual network cards. You can assign each of the virtuals a different MAC and have the real MAC on the (real) bridged device to whose the virtual ones are connected to in bridged mode. Above link explains how that can be set up.

    If it does not work for you, you will need to re-define your requirements.

    But you should be aware that if you plan to expose these virtual ones to the world, you will need to buy network cards and type in the MAC address of those, in which case you can even plug them in as that yields to better performance and is easier to setup. In general I would advice not to use virtual ones unless it is not otherwise possible due to physical problems like i.e. lack of PCI slots.
