The Samsung part on the K3 is the smallest capacity of a family of parts that share the same package and pin-out (ball-out?).
For someone with access to the special tools required for SMD re-work, replacing the eMMC chip would be an interesting challenge.
But who keeds a K3 with a 64Gbyte eMMC chip?
And not to forget the software changes that might be required to ensure the Samsung recommended write alignment behavior.
(App. note referenced in post above.)
If the O.P. is still around, this might be a good chance to actually do a significant hardware modification to the K3.
