Here in the extremes we have; it is nice to plan HIGE & we do, but then the conditions change when You get there & You have HOGE on arrival
but then next time again the conditions change so much that your so far less than HIGE You gotta drop something off down the valley
So basically this is no environment for those lacking in experience & not knowing their machine
There are NO twins that will work at these ultra high altitudes & DA's so singles are it....in fact only 1 at super high altitudes the AS350B3
As for plan B go-around options
hmmmmm try going into the Western Khumb a dead end valley with 27,000' to 29,000' mountains surrounding You on 3 sides, it's one way in & the same way out with no go-around options & no HIGE landings around 23,000'+ every time
done only to save a Life
