For ash killing bones, the preta path's blocking technique absorption seal can be used. This technique erects a barrier around the user and whatever chakra based attack comes in contact with the barrier will be absorbed. The barrier does not allow the attack to enter inside,till now no attack has entered that barrier when nagato had used it. The barrier allows absorption from all sides. Nagato's rinnegan can just enable the barrier within seconds. For TSB. I feel that unless you possess sage of six path senjutsu ,you cannot absorb TSB. Though going only via statements TSB is ninjutsu and preta path can absorb all ninjutsu.
