Limited/Event Costumes in Pearlshop

Hey,
I would like to suggest that the Costumes that were only available for a Limited Time or During Events get added permanently to the Pearlshop.
So the players, that missed them on the Retail can buy them on GamezBD.
In my opinion there are pretty cool Costumes like the Halloween ones or the Christmas costumes.
I know they were only available for a limited time, but we're on a Private Server so why couldn't we get these also on here permanent in Pearlshop?
I'm not sure if this works but if it does it would be awesome.

- This is my personal Opinion, so feel free to give me your Statements if you agree or disagree. -

 

You might be right. Thank you for your suggestion
