Water Damage iPhone X - Logic Board

Hi,

I have two iPhone X, one has a bunch of pictures from a recent vacation in which I had no connectivity, wifi, cellular or otherwise -- and therefore has no backup. That iPhone X has water damage and does not power on. The other iPhone X is brand new and fully functional.

I have torndown (carefully) the damaged iPhone X and have discovered there is no (visible) water damage on the logicboard. Is it technically possible to switch the logicboards to recover the pictures/data from the damaged iPhone? I'd be switching water damaged iPhone logicboard to the functional iPhone under the assumption that the issue with the damaged iPhone is not to do with the logicboard -- and that logicboards arent somehow tied to other hardware components on the iPhone.

Note that I understand this would void all warranties and break the (alleged) water resitant nature of the functional iPhone.

Thanks
