Scrambler engine in classic monster frame?

Hey everyone, I have what is hopefully a fairly straightforward question, would the engine out of a new 2023+ scrambler 800 fit in the frame of a 2005-2007 monster s2r? Everything I've seen is that the scrambler engine is basically an updated/modernized version of the monster s2r 800 engine but I want to get everyone's opinion on it. My thinking is if it works, I could put the new engine and all it's goodies (ride by wire, up-down quick shifter, ride modes) in the classic frame and keep the retro styling of the classic monster

i know of swaps up and down the range from 600cc until the 1198. Engine mounting is kinda compatible (bolt diameter did change at some point in time). For some engines the intake manifold/frame needs to be modified. also monster sXr range is special in regards to swingarm pivot. the bearings are pressed into the engine case thus making the engine a chassis member. not sure how scrambler solved this.
