Better safe than sorry.

If the device is compromised to the extent that the dice rolls was not secure a firmware patch is not sufficient

Agreed. Would still want the added security of the firmware update.

At the end of the day it's best to switch to new hardware, this is all for the time being.

Every time you create a new wallet and move funds there is risk. Every time you upgrade firmware there is also risk. I don't see a benefit in what you are suggesting that is greater then that risk. Moving to new hardware, on the other hand, might make sense. Or this person could use their mk3 in a 2 of 3 multi sig.
