Therefore, if someone was to write a specifically lossy encoder to PNG (whyever one would do that), it would be a more efficient compression than JPEG->PNG.
It would remain to be seen if it is more efficient than storing it as JPEG in the first place.
Meanwhile we could start using more efficient lossy formats for cases where the lossy model is preferable, like WebP or, if - hopefully - it takes off, a Daala-based still image format.
