But as for using some offline phone as the hardware

wallet, wouldn't a phone already cost more than a hardware wallet? The cheapest option which supports apps are KaiOS devices and they already start from like 50 USD. The cheapest trezor is 49 USD

These options are not available everywhere in the world. But do you folks think a software to turn a cheap KaiOS phone into a hardware wallet a good idea?

A KaiOS device in the most expensive case is not more than $100-$120. And I've bought my Nokia 800 Tough for half the price because it was open box and used for a few months. And if you are somewhere the carrier sells locked phones, you can buy one for only 15-25 USD. The idea is replacing the System app of KaiOS with your own custom system app which is specificly designed to sign the transaction and show a QR code of it, or transfer it with Bluetooth if there is a secure protocol for doing so, similar to hardware wallets. If you want even more security, you could replace stock OS with postmarketOS.

It depends, as long as the data gets encrypted with a strong password within the phone it should be okay for offline hardware wallets. Hot devices will be a problem since I am assuming those devices may have a weakness because of price and manufacturers cutting corners

I think QR is a bit more secure than any wireless connection. But I heard those codes could be changed to trick the wallet to leak other information that later can be reconstructed to force guess your private keys.

I get a phone for $15 every year from my mobile provider. I don't discard them because I know I can use them later.
