W216 2010 CL63 Engine swap m156 to m157????
I need your help and advise

I have a 2010 CL63 with 78k KM on it (m156)
the belt and pullies had to be replaced I've waited for 10 days for the parts to arrive.
and after just 1 day of pullies and belt replacement, the engine just died.

just bought it and I only drove 3 times.

oil pump failed and ruined the whole bottom of the engine, you know the rest.
my mechanic, quote me a long list of parts needed to rebuild it. Pistons, crankshaft, piston rings, oil pump, engine (timing) chainset and many other parts.
since currently I don't have any authorized dealer or workshop around and concerned about the result and process, I've decided to replace the whole engine
now I was wondering should I stay with M156 or I have the option and it's possible to go for M157? if it is which one should I chose?
I decided to keep the car as long as I can upgrade to C217 and it won't happen in the next few years or let's say another 30k KM
so reliability and maintenance cost has to be considered.
I know if I decide to swap the engine with m157 the ECU has to be changed but what about the transmission and fitment?
do I have to modify the engine mounts?
it is my first thread so please forgive me if I didn't do it great.
thank you all in advance
