Yes, you can swap the whole frame and top from another car (plastic window or 2003-2004 glass window) in about an hour. I replaced my plastic window top on my 2002 with a 2004 OEM top using the instructions I will try to attach below. The same procedure would be used to swap another plastic window top/frame unit. It was surprisingly easy. Good luck.
I couldn't attach the pdf so here is a link to Mike Focke's page on the subject. Open the pdf files on the bottom of the page for instructions and pictures.
