I would not recommend that because to access his crypto user would need to save derivation path (besides SEED) for each coin he want to keep. This may be confusing for man especially if him is kind of newbie.
It doesn't need to save any derivation path. You only need to write/keep 12/24 mnemonic seed on paper.to know receiving address (public address) each coin, select coin tab.
to sending and payment using Bitcoin, eth, xrp or any coin, use BIP39 compatible wallet such trustwallet, coinomi etc.
