I've a recollection that adding all the keys to woodwind instruments
wasn't just about being able to add extra notes, but because some notes
can fit better with a fully chromatic scale if the holes are all
different sizes, including some that are too big for fingers to cover.
There's an article about it here,

Would this give us any benefits? Even if it would, it sounds as though
it would require a complete redesign of the chanter as well.
