More Human-Like Secretary Birds

So, I am dealing with a certain trouble that I'll need a help with.

In my fantasy story, there is artificially formed species (magically created, but non-magic anatomy rules apply) of "humanized" secretary birds.

By "humanized", I mean:

1: They are able to grasp objects with wings (perhaps fingers). They might be less dexterous than when using legs, but at least should be able to use them to throw stones/spears.

2: They need to be able to bend their wings in a way that would allow them to throw stones/spears they grasped in them.

3: They have intelligence on par with humans. Maybe, they're able to get away with a slightly smaller, more efficient brain, but there's definitely a need to scale up their head.

4. Slightly larger than an ordinary secretarybird with total body mass of around 8-10 kg.

What I want to avoid:

1: Completely changed "furry" creature - I do not want a creature that is basically a human in feather suit, my goal is to opt for minimal anatomic changes to fulfill my requirements.

2: While my plan for them is to be basically incapable of regular avian flight, I still wish for them to be able to glide for short distances, if they start from a high ground.

My question is this - are these changes anatomically feasible? Or am I making too many changes, and it is not possible for all of these requirements to be satisfied at the same time?
