This is extremely UN-recommended!  The hashes in the directory and
file names of the *.eln files are designed to make sure, with high
probability, that you never load a .eln file which is incompatible
with the Emacs you are running, because doing so will almost
certainly cause a crash at some point.

So you are well advised not to do that, even if Emacs gives you enough
rope to hang yourself.
