Shanty Columns Skin

[RiotZ]

I was planning on making an unusual type of map, sorta like an RPG but more free roaming, "Just-Do-Whatever-The-Hell-You-Want" gameplay. So I planned on adding a Arena for making money and screwing around with friends. The only doodads I found that fit were the big white dalaran columns.
Could you make a version of these columns that wasn't so clean and well constructed, making dark gray, with massive cracks and bits of moss, stuff to make it look old and shanty.

Here's a screenie:

You'll have the ruined versions of the columns, found as doodads in Dalaran Ruins section. Otherwise, you could blend some doodads. Let's say, you place a few hanging mossy green thing from the Sunken Ruins section on prefered columns. Columns from the Sunken Ruins are good too for making an old impression. However, I recommend the Dungeon columns. The dark ones.

Btw, you can use pathing blockers on columns without pathing.
