I understand the processor and radio differences.
It will take much more than what is listed in the OP. I am not sure I have ever seen a ROM ported from Europe to the US (or the other way around).
As you mentioned, the processor and radios are different, but so are the system partitions. Anything is possible, but I think that would be a huge amount of work.
If you try this please be very careful. Many, many users have bricked their devices flashing a ROM from across the pond.
