How to rekey or merge consecutive json key : value pairs into a field?

[Glasses]

So I have the following _json event that I need to wrangle into a more useful format.
As you can see there are 2 key:value pairs that are related, e.g name = and value =

For example I would like to combine the following into 1 field like a re-key, but do it globally for the entire source.

name: target_user
value: rey.skywalker@jedi.com

name:target_user,value: rey.skywalker@jedi.com or target_user= rey.skywalker@jedi.com

any suggestions appreciated, I tried a props and transforms on the search head with no luck.... thx in advance
