N55 Engine compatibility

[mrvedit]

I'm helping a friend find a replacement engine for his 2011 X5 which spun a rod bearing. It is a N55B30M0. Since I can get local engines from e.g. a 2014 X5 or a 2013 335xi, I'm trying to determine if these could be used. I know that the x-drive oil pan and accessories might be different but these can be swapped. If I can get an identical part number block and head, I'd be happy.
Compatibility guides tend to be too conservative since many/most people would not be willing to swap the oil pans and/or accessories.

Anyone have experience with this?
Does anyone know the block and head part numbers for a N55B30M0?

According to Wikipedia, the N55B30M0 was used in these vehicles:
