Are you saying that if I chill my water ice with liquid nitrogren or CO2, that ice will take longer to melt than either of those by themselves?

Yes, but you'll use more than 2kg of LN2 or dry ice for each kg of water ice you chill down to those cryogenic temperatures.

Maybe. The -125C ice could melt faster if it and its container shatters into a billion pieces (a real risk if it’s dropped), massively increasing its surface area.
