Nexus 4: Is there a "surgical" way to retrieve data from storage?

Nexus 4: Is there a "surgical" way to retrieve data from storage?

Nexus 4 took a dive in the ocean (salt water) and now it is resting in a
rice bowl. While we all hope for a seamless recovery, I understand all the
corrosion niceties salt water brings to the party.
However, the phone has unsynced pictures/videos that I'd like to retrieve.
Connecting it via adb/usb/otherb is not an option of course, since it does
not turn on.
Is there a more intrusive/surgical way to get to the data? I don't mind
soldering that storage out and connecting it to something that can read
it.
