Hi Paul and thanks for dropping by :)
I had another look over the depth factor when using Teleconverters and i'm afraid i had it right the first time. The effective depth gets doubled. Here is a quick link for that:

I think that with conversion lenses or even maybe extension tubes, the situation might be as you mentioned.
Anyway, thanks for your visit
