Okay Minor points first. There are actually two different forms of henge in Naruto. The common one everyone knows is pure illusion. It takes significant chakra to change physical reality in that way, way more than could ever reasonably be expected of small children.
The one Naruto, and some of the more high end characters in the setting, is a full physical transformation. This is demonstrated by Naruto turning into a windmill shuriken to be grabbed and thrown. He even transforms into a rasenshuriken in the fight with Pein to fake out chakra absorber. Boy really COULD turn into a bird if had the necessary creativity and desire.
Now onto Anko. I chalked up her devotion to Daisuke, and her desire to please him at all costs, to his singlehanded murder of the person she hates above all. Orochimaru quite literally ruined her life, and semi regularly attempts to existentially threaten her home. That hasn't happened here, and as such canon Anko remains the characterization model without much added or changed yet.
I do like that she's reasonably open, actively considerate, and direct. I'm betting on that being a combination of factors. She's warmer to him than she is to a lot of initial meetings. She was almost certainly briefed on his background, feels some degree of similarity, and figured this approach would be most optimal for starting on good terms with a not particularly social person. Even without the kinship bonus to disposition, regular S rank pay CANNOT be turned down, and smart people want to be on good terms with long term clients.
I wonder how she reacts to meeting little Naruto earlier, and in a different context.
Finally, were I in Daisuke's position, I'd balance ninjutsu and seals more evenly, what with Ninjutsu being the fastest path to a diverse and easily usable ranged moveset to compliment the punch, but I understand the desire to rush seals.
