ePub to ePub?

[mojofleur]

Hi there...

I was wondering if there is a simple way to batch convert all of my ePubs in a "calibre-friendly-epub", in order to:

1. Have my books standardized (margins, fonts, line spacing)
2. Have the cover embedded in the file (since I use a Nook Touch, that would be pretty useful)

Have the old ePubs deleted at the end of the converting process would also be great!

So? Any suggestions?
