I would think that (g)parted should be able to do it, or any
other tool that can move a partition without changing it.
In a pinch, fdisk + dd_rescue (copy from the end for moving
towardfs disk end) can do it, but that is tricky and requires
manual calcul;ations that have to be right. 

However LUKS/dm-crypt itself cannot do it, as it is not a tool
for dealing with partition information or moving data. The
task is simply out of scope. 

Before you move, make a backup. It is far too easy to
damage vital information in this type of operation.
