This is a npc to pc polymorph just like darky999's and the one my brother made for L2J-Archid. Well its not so advanced as them but this dose the job right, it polymorphs with the correct packet length. 
Heres a picture of a pre-made SQL Entry named Alex:
Features:
- It supports null name and title
- No item id Weapons
- Armor set parser to add a armor set to the morphed npc Smiley (like you see in the picture Apella set id 49)
With all that said heres the code:
And sql:
