Possibly. You will have to run it through OCR and your scans have to be in very good quality and resolution. You might possibly need to convert the scans into a file that the OCR can read. I haven't used OCR in years so I don't know how good they are these days...
After it is converted into text you obviously will have to convert it to ePub for best results using Calibre or similar software.
And after that yes, your Nook will be more than happy to read that ePub
