And things that go bump in the night

I had created some ghosts using the Ravenloft system (Van Richten's Guide to Ghosts) several years ago. I'd actually like to convert mine over to 3.5 for the BR setting.

Has anyone converted ghost magnitudes and salient abilities into a 3.0 or 3.5 format?

I've seen the basic D20 article in the wiki, but it doesn't address the above.
