Wow, that's a great idea! It makes my code looks so much cleaner.
Compare:

polyPts = vertices[0:1,0]
polyPts = [[polyPts],[cartPts1]]
polyPts = [[polyPts],[vertices[0:1,1]]]

and

push, polyPts, vertices[0:1,0]
push, polyPts, cartPts1
push, polyPts, vertices[0:1,1]

Here's the new code: http://idl.pastebin.com/B0gm95pW
