I have been using a free Microsoft post processing package, ICE, that merges multiple images. It is not just a panorama merge; it merges vertically and horizontally. I would try that. Do shoot from a tripod because if you do more than rotate the camera vertically and horizontally, you may get some breaks in the image.
I've had pretty good results not going wide angle; shoot regular lens with multiple overlapping shots to cover the area, and stitch with ICE.
