It seems impossible, because, while looking the same, the destructuring assignment and object syntaxes are completely different things.
let a, b;
{a,b} = x <-- {a,b} is not an object
If you try returning the result of destructuring assignment, it will still be returning x, the full object.
const result = {a,b} = x
// `result` is the full object
or
const result = ({a,b} = x);
// `result` is the full object
Anyway, writing such one-liners could be extremely confusing to teammates. It would raise my eyebrows during a peer review anyways :)

I think what you need is to filter the object by key without middle variables.
Here is my solutions:
let x = {a:1,b:2,c:3}
let y = {}
;({a: y.a, b: y.b} = x)
let filterObjectByKeys = (object, keys) => Object.fromEntries(keys.map(k => [k, object[k]]))
let x = {a:1,b:2,c:3}
let y = filterObjectByKeys(x, ['a', 'b'])
Reference:
- Assign value to new object via destructuring
- Filter object properties by key in ES6
