Hexhead K26 engine block swap compatibility with K28 1200 ST

Hi all,

One of the timing chain guide rail broke in my '07 RT. The engine block is clocking 120.000km and I am thinking about swapping it by another one instead of changing the guide rail (which would require a huge amount of work and tools I don't have).
I found a second hand engine block from a 1200 ST with very low mileage at a decent price. From the BMW parts catalogue, the engine block is common and shares the same reference between the K25 ('07 - '10 GS), the K26 ('04 - '10 RT) and the K28 ('03 - '07 ST).
My question is simple, are these engine blocks similar? Do you think that I could just swap these?
Also, my bike has a board-computer with an oil level switch sensor. In the case the engine I purchase is from a bike without board-computer, do you think the sensor can be transferred from the old to the new block or is it completely sealed off?

Thank you very much for reading and replying to my questions.
Wish the best
Flo
