[Feature] face detection, change feature photo => list of possible thumbs, ordered by a "quality criteria"

The feature

I have seen in feature descriptions, that in the future selecting the best match for a person will be improved.
Would it be possible, to add some improvements also to already detected faces?
I could imagine the following:
When I click on "change feature photo", then I get a list of sorted feature photos, sorted by using some "quality criteria":

• distance to the average face vector
• thumb quality (size, sharpness, ...).

If the "select thumb algorithm" will be improved, the same code could be reused to order the possible thumbs.
