Will the skeleton spritesheet be able to replace the player spritesheet permanently (or until the player changes back), by using a potion or doing a future quest?

Technically not yet.

If the gods of tech dev decide so, perhaps eventually. (Well, since we're planning races anyway, the player base spritesheet should be dynamic on the long run. Probably no one is going to bother for eAthena even if we could abuse the class sprite system.)
