The way to secure a wallet isn't by your laughable Rube Goldberg machine.
Generate a wallet on a dedicated airgapped machine, write down some of its addresses, encrypt the wallet and back up the encrypted file. Then send BTC to the addresses.See how that works? Now you have a bank from which you can make withdrawals to smaller wallets. Use your brain to figure out how.
