Copying the context of a driver object to another one

when i create a driver and a device object like this:

PDRIVER_OBJECT fakeDriverObj;
OBJECT_ATTRIBUTES DrvAttribute;

InitializeObjectAttributes(&DrvAttribute,
    &dr0Device->DriverObject->DriverName,
    OBJ_PERMANENT| OBJ_CASE_INSENSITIVE| OBJ_KERNEL_HANDLE,
    NULL,
    NULL);


auto fakeDriverObjSize = sizeof(DRIVER_OBJECT) + sizeof(EXTENDED_DRIVER_EXTENSION);

NT_ASSERT(*IoDriverObjectType);

 status = ObCreateObject(KernelMode,
    *IoDriverObjectType,
    &DrvAttribute,
    KernelMode,
    NULL,
    fakeDriverObjSize,
    0,
    0,
    reinterpret_cast<PVOID*>(&fakeDriverObj));



memcpy(fakeDriverObj, dr0Device->DriverObject, fakeDriverObjSize);

dr0Device is a real device from a real driver, and i associate the created device to the created driver like this :

 fakeDeviceObj->DriverObject = fakeDriverObj;
 fakeDriverObj->DeviceObject = fakeDeviceObj;

is this even valid ? i mean when i do this :

 g_originalDeviceControle = fakeDriverObj->MajorFunction[IRP_MJ_DEVICE_CONTROL];

calling g_originalDeviceControle() will be like calling the original driver ?
