What problem are you trying to solve?
It seems there are a few cases where people would like to use derivation paths not currently supported by MetaMask.

• Add HD path option m/44'/60'/0'/0 for Ledger wallets. #6716
• Use Trezor address derivation on Ledger #7238
• I myself would like to use the path 44'/1'/0'/0 for my Rinkeby accounts since this is also what Frame uses for Rinkeby accounts.

Describe the solution you'd like
I think rather than adding every possible derivation path users could want as a pre-set, MetaMask could simply give users the ability to set their own derivation path when setting up the wallet, for software and hardware wallets alike.
