We ought consider using QOI instead.
QOI is often equivalent or better compression than PNG, _before_ you even compress it with something like LZ4 etc.
Compressing QOI with something like LZ4 would generally outperform PNG.

QOI is really cool, but I think the author cut the final version of the spec too early, and intentionally closed it off to a future version with more improvements. With another year or 2 of development, I think it probably works have become ~10% more efficient and suitable for more usecases.
https://github.com/nigeltao/qoir has some numbers comparing QOIR (which is QOI-inspired-with-LZ4) vs PNG.
QOIR has better decode speed and comparable compression ratio (depending on which PNG encoder you use).
QOIR's numbers are also roughly similar to ZPNG.
