Combining the elements of array and reformatting the output

I am having an input JSON which I would like to transform using Mule's dataweave 2.0.

Below is the input JSON.

[
   {
     "data1": {
                "role": "analyst",
                "name": "ABC"
     },
     "data2": {
                "role": "analyst",
                "name": "DEF"
     }
  },
  {
     "data1": {
                "role": "RM",
                "name": "PQRS"
     },
     "data2": {
                "role": "analyst",
                "name": "QWE"
     }
  }
]

We would like the output as below :

[
  {
     "role": "analyst",
     "name": "ABC"
  },
  {
     "role": "analyst",
     "name": "DEF"
  },
  {
     "role": "RM",
     "name": "PQRS"
  },
  {
     "role": "analyst",
     "name": "QWE"
  }
]

I have tried different options using map, pluck and flatten, but could not get the solution. Please help me with the transform function for this.

If you want to keep the order you can:

1) Go through the elements with reduce and for each object in the array, accumulate data1 and data2

%dw 2.0
output application/json
---
payload reduce (item, acc = []) -> (acc << item.data1 << item.data2)

2) Using map, for each element in the array create an intermediate array containing data1 and data2 and then flatten that.

%dw 2.0
output application/json
---
flatten (payload map (item) -> [item.data1, item.data2])

If the order of the objects in response is important:

%dw 2.0
output application/json
---
flatten (payload map (flatten $))

If the order is not important:

%dw 2.0
output application/json
---
payload.data1 ++ payload.data2
