I suppose you could do it, but no, I've not -- there is a large crossmember under the rear half of the oil pan, and I'd personally not even try to replace the upper oil pan half with the engine in the car, way to difficult.

If you do decide to do this, take a good look at the cylinder bores before you remove the oil pan. If there is a distinct ring ridge and the wall as shiny, no honing marks visible, new rings will do nothing for you.
