Trent and Julie,
Personal opinion is no, as DSLR sensor performance varies too much.
However, give it a go and see how it turns out. Whilst you're at it, take some flats and flat darks.
If your lens and sensor were fairly clean and you can get your focal length and focus back to where you had it at the time of image capture, you may able to sort out the vignetting.
Take your flats at ISO-100. Point your camera and lens to your notebook screen, load Photoshop up and create a new document with a white background. Hit 'F' a couple of times to go into full screen mode and hit Ctrl++ a couple of times so the document fills the screen. There's your flat field! Take 15, or, so (you want an odd number of frames for the median combine algorithm to work effectively). The same rules also applies to darks and flat darks. Take a few test flats and check the histogram. You want the curve to peak somewhere between 1/3rd to halfway across the X-axis.
Hope this helps.
