Out of yes or no, of course my pick is yes!
Currently it's implemented as face makeup, and that of course should stay/have its functionality restored.
But the real kicker is that Mind Ark's game has an actual system for user drawing/painting, and it's robust enough to create those amazing masks you've linked already. What's being created is a typical square texture that just happens to end up mapped to the face, but could really be put on just about anything, provided it was modeled/UVd with texture continuity in mind.
This system already has hooks for taking items, which already slots into loot, skills, and thus the overall economy... there's so much potential here and there's not a whole lot else out there like it!
