Chakra can change over time but it would still resemble that persons chakra. One of the things that made Kabuto notable was that his chakra sig was altered to the point that it was unrecognizable as Kabuto's. Perhaps merging with the tree made the drastic change to her chakra that made it impossible to recognize her.

Transmigrating is a different from Bijuu regeneration because Ashura and Indra's consciousness' arent passed down.

I haven't seen the last in a while but i don't recall Hinata being able to see spirits. Also what do you mean she was exposed to more Kurama chakra?
