Fun changes to album cover

My brother-in-law is a mad Beetles fan. As a present I am going to make 10 little changes to the album cover of Sargent Peppers Lonely Heart Band and print out the new cover to give to him :-) I've included a high-resolution picture of the cover and a file with the changes required on it. It is fairly straight-forward but I do not have the software to do the cropping of the photos properly and to insert them in the cover. It is important that the changes look part of the album. Thanks for your bids. Louis
