i just figured that its the wallet gets compromised somehow thru firmware, everything is gonna be compromised
so thus im thinking 2 of 2 multisig with a trezor and ledger with strong passphrases on both
i just have to keep two sets of words safe Wink

yes I think it would increase the security but have you figured out how to do it?
each wallet will have 1-part private key derived from its own seed to be used to sign a multisig address
then your software on your pc uses public keys from both devices to create multisig addresses
one multisig address for each derived address from both devices
is there a mechanism (easier way) exist to do such thing like HD multisig wallet?
