the real question is
Couldn't Momoshiki absorb Sasuke and Naruto themselves and eat them like he did to Kinshiki??
Sasuke's rinnegan is superior to momoshiki's over glorified preta path rinnegan :Sparks:, momoshiki couldn't absorb sasuke, sasuke would do to him and candy vegito did to super buu :Sparks:
Naruto can't be absorbed, he'd TNJ him to death :Sparks:
No but seriously I think one has to be severely weakened or WILLINGLY give themselves up to momoshiki to be absorbed that way, also it appears that it takes some time to prep and the opponent must be stationary, idk that's what happened to kinshiki so I'm going off of what occurs, on a plus note, it's sort of like human path+preta path in a sense.
