Would replace key work in this specific multisig case?

In the time-sensitive scenario where someone wants to make a transaction on their 2 of 3 Sparrow multisig wallet but has only 1 hardware wallet available but has all 3 seed phrases, would using the replace key feature and entering one of the seed phrases(not the one on hardware wallet) work in allowing a second key signer that could be used?

Notes: This is a time-sensitive scenario so I’m assuming not enough time to ship a new hardware wallet. Also, I do realise the single hardware wallet could be used then factory reset and loaded with one of the other 2 seed phrases. However, this then creates a potential problem if that device is somehow compromised. I realise entering the seed phrase into a software wallet(when using replace key) is a big no-no, but as I said this is a theoretical time-sensitive scenario ,and if it can be done, there are ways using Tails on machine not connected to Internet that would make it potentially safer than the alternative of reusing the hardware wallet.

Many thanks
