We don't know. :| Preta hasn't shown limits. Sasuke can sense nature energy and has experience with curse mark so he should have the skill to control the flow of nature energy in his body like Madara did. (Sasuke also has Hashi cells)
Anyway it's possible, but we can't say for a fact
Sending natural energy and having the CM isn't the same as being able to balance it with your chakra though. Juugo clan can sense natural energy but they couldn't control it and would go berserk. CM does all of the work, Sasuke is just using the imperfect Senjutsu CM produce so he had no experience controlling natural energy nor knew what it was when Kabuto told him about it. Sasuke should be fun absorbing Senjutsu which is already in perfect balance but if he grabs Naruto as Naruto absorbs in more natural energy then he'll turn into a toad stone.
Also you need to know how to be completely still to learn to perfectly balance natural energy which Sasuke doesn't know and it takes training to do since its using chakra control differently; its internal at the molding chakra stage instead of after already molding chakra.
lol at this thread.
sasuke can absorb all of naruto's attacks.
the only question is SM charka, but sasuke has been using a imperfect sm since part 1
so its safe to say he can handle it
I already explain it above, Sasuke has no training or experience balancing natural energy; he only used imperfect Senjutsu that the CM gave him. Being completely still is also a requirement that Sasuke never needed to train in and it's not like everyone can train to be still, it can be impossible for some.
O.T. As far as I know Sasuke absorbs through his hands like Madara; if he can absorb using the barrier like Pretha Pein then he can absorb from all angles but if not then if a Naruto uses multiple attacks then I don't see him absorbing fast enough to absorb them all and will get hit by the rest. If Naruto somehow learned to imbued his attacks with Yin Yang to negate ninjutsus then that could make Naruto's jutsus unabsorbable.
