'Pseudononymization' is how my brain read it. It's a fairly self-explanatory portmanteau with little chance of confusion on the root.

"Pseudonymization but with an extra syllable" sounds just as confusing as the other two. I wouldn't be sure which of those words I was looking at on first glance, which is what you'd need for it to be casually readable.
