Should be possible with a Model T, but not Model One.
I would recommend a 2 of 3 setup just in case you lose access to one. For example 1 Trezor, 1 Ledger and one additional seed stamped into a metal plate or something.
That way when you want to do transactions you can use it just like you would use a 2 of 2, only needing your Trezor and the other device (e.g. Ledger). And the third part of the multisig would ideally never need to be used, just acting as a backup in a scenario where you lose on of the other two.
