Swapping n52's

Hello!
I own an euro 2007 e92 330i N52B30A 272hp (black valve cover).
Recently one of my pistons decided to go to a better place and take one of the valves along with it.
I'm looking into an engine swap, but can't source the same engine locally, most of them are from E60/E90/e63's with the silver magnesium valve cover.
Wondering around realoem led me to see many different part numbers for engine block, pistons, rods, and other things.
Would I be able to swap an n52 from an auto e61 to my e92?
PU92278 - my last vin 7 digits
CC68257 - the e61's last 7 digits.

Both are n52b30's. The e61 has 190kw and mine has 200kw.
Discussing with fellow owners on Facebook groups led me to believe that as long as I swap my intake manifold, oil pan, and valve cover over to the new engine everything should be ok, as the long blocks are basically identical. (Disregarding the fact that my "updated" n52k has bigger valve stems and so on.
First photo is my engine from e92, second one is the one from the e61.
