multiselect hash from nested dict without knowing key names doable?

Hello

I'd really appreciate some help with the following structure
```
[ {"a": [ { "b": { "foo": { "c": { "bar": { "value": "123" } } } } } ] } ]
```
Where I know the names of all the keys except for `foo` and `bar`, and would like to return those key names when 'value'=='123'

i.e. something like
```
[].a[0].b.[@1].c.[@2].[?(value=="123")].{ firstkey: @1.key, secondkey: @2.key }
```

No idea if what I'm asking is possible.
