Based on the explanation given, it should be able to absorb the chakra component of the ash bones, yes. The bone would remain. I'd expect that being hit by a bone is infinitely preferable to being hit by an instant-kill bone.

TSB's are unclear, because these things themselves are unclear. They don't seem to obey the normal rules on ninjutsu, since they form without apparent user interference. Not just that, but Naruto used them to make Bijudama Rasenshuriken, yet they returned unharmed afterwards. This implies that there's more to these orbs than merely being a 5-element combo. speed is another factor in Ash-killing bone ash technique. Rinnegan mostly wont be able to completely absorb ninjutsu part before it hits. For TSB, it would be kinda of anti-climatic if they can be absorbed easily by rinnegan without any recuperssion.
