It should think it wouldn’t take THAT much. I’ve made homebrew surround mixes of it. While there’s a lot of panning going on in the stereo mix, there aren’t that many elements to juggle.Can you imagine if someone could get hold of the multis and do a 5.1 mix on some of these?
I'm hoping that all these Atmos releases by The Beatles, and now Who's Next, will compel Led Zep to do some Atmos remixes of their catalogue lest they get left behind. I suspect that remixing a song like Whole Lotta Love would require a mammoth effort to get all the special effects to sound like the original stereo recording.
Now whether - precisely because of that - it could possibly meet people’s imagination of what it could or should be is a different question.
