Hmm...just tried it myself with a test sim in SimPE, and it doesn't seem to work--I can add them into a household, but they don't actually appear in-game, probably because SimPE says they have no character data.
Tried again, in-game, with both the teleporter shrub and boolprop in the family I'd added them to in the first place and an unrelated family--no luck there, either. Looks like the deleted sim is gone for good...oh well.
