Yes, I guess so. PDFRead supports command line mode, and paperCrop uses LUA script for generating output. So one who are familiar with LUA script can modify the .LUA files in the scripts folder such that the output images from PaperCrop are automatically converted to e-book files using PDFRead. But at the moment, I don't want to do the work by myself due to my lazyness.
I can provide the codes of paperCrop to anyone who are interested.
