In before the lock...
The problem with the requested upgrades is the same one that has existed since launch. Where are you going to find an SoC with the desired characteristics that can take PoP RAM and at an acceptable cost to maintain the retail price?
The SoC is the main issue there. Having the flipped chip and metal case precludes the use of PoP RAM, so therefore this would be impossible.
As for USB3.0, the USB controller on the Pi 4B is external to the SoC and connected via a PCIe bus. That would mean the proposed Zero would need a USB controller chip too - still no board space for that - unless a completely new SoC is designed just for the Zero, which would be impractical.
OK my reply was a bit harsh, but it has been asked and regurgitated many times.
There are a range of products
$5 Zero, $10 ZeroW, $15 ZeroWH, $25 3A+
It is clearly stated that they are planned to be available for another 4/5 years and therefore if as the OP suggested they make a product to his specification and Zero price point ( unlikely ) it would decimate sales of current products
Then there is the fact as stated above and in many other posts that a complete redesign would be required.
So yes it is a post posted without any due consideration of what they want may not be either feasible or viable.
Yes memory prices do go up and down but PoP memory is a niche market.
Bottom line is research, research, research then post a costing of BoM.....
