Yeah...no thanks.
I realize I’m probably in the minority here, and that strictly speaking there’s nothing sacrosanct about a particular method of torturing people (not least because it’s torture, and also because the Romans did it to loads of people), but being in a scene with PCs yelling “Crucify him!” as someone is flogged and led away is still going to feel like sacrilege to me, the player.
Kill people by the same mechanism, but call it something uniquely Zalanthan, on a shape other than a cross (like how the Cuddler is essentially just a medieval Rack), and I’d be fine. (Though I’d still hate to be the player trying to stay engaged as my PC dies a powerless, agonizingly slow death, FWIW.)
