Playable ghosts in household?

No, you can't. Ghosts cannot become members of the household. If you want to have that sim playable again, you'll have to resurrect them.

I have used testingcheats to make a ghost selectable. They have one interaction: Haunt. If you cancel that, they'll go back into their grave.
So you'll have to use mods. I unfortunately don't know any, but I hope someone else knows.

If you have Simpe you might be able to do it. There is a set of ghost features in the character sheet. I've frequently checked off the go through walls and objects for certain playable sims to reflect them having certain special abilities, which works just fine. I've not checked 'is ghost', even as a test, so cannot speak from experience. I think you will get a ghost, but have no idea if it would be controlable.

Ghosts are not meant to be playable in Sims 2. I would highly recommend against making ghosts playable. Or making a living Sim a ghost in order to do so.

Just because you can do something in SimPE does not mean that it is wise to do so. You can make it to where you have to repair or reinstall the game and/or lose neighborhoods if you do the wrong thing. And you won't necessarily know right away either.

You can try the transparent skins - http://modthesims.info/d/161350/transparent-skin-recolors.html
