As said before, the resurrection spells can't duplicate a body. You may, however, want to look into the various magical abilities that do let you duplicate a body. Whether the PCs must be compliant in this act or not is debatable, so be careful if there are any rules-lawyers in your group.

This list is hardly exhaustive, just what I could find that met the criteria with a quick search. There's also the option of creating a golem and shaping it to look like one of the PCs. In the same way, Create Undead and then Seeming to make it look like a PC. There is also always Wish and Miracle, which can duplicate any of these spells. It's really up to personal preference, and remember that you always have the option of just saying "a wizard did it".
