So in addition to a new feature in Selectors, you’ll need to get 
Selector API (now defined in the DOM spec) updated, as it explicitly 
defines that the return values (either NodeList or Elements) can only be 
elements and not other types of nodes.

Additionally, Attr is not a Node anymore and therefore can not be part 
of a NodeList. (Note in [1] the lack of interface inheritance compared 
to [2].)

[1] http://dom.spec.whatwg.org/#attr
[2] http://dom.spec.whatwg.org/#element

Today you can already use these API to select elements, then use 

How would the APIs work with your proposal?
