Alternately you could be really brave and create a Teleport folder for Life Stories:
~(My) Documents\Electronic Arts\The Sims Life Stories\Teleport
and use Sims2Pack Clean Installer to install the lot (with the sims2import script!) to that Teleport folder instead of the TS2 Teleport folder
I tried this myself and found that it didn't work; too many of the files want to overwrite each other when doing this, for some reason, and those that remained did not show up in-game.
What was successful, however, was using the S2P Clean Installer to extract the files to the TS2 Teleport file as usual, then simply moving those files to my new SLS Teleport folder. Now I can have my little lots again!
Hopefully this method works universally for installing lots.
