Oh yes I've done them.
You have two options. Remove the engine/transmission from the RTV and then do it on the bench. Option #2, cut the crossmember out and re-weld it back in so the skid plate can go back on. Or leave the skid plate off, but that oil pan is subject to dings/dents/etc without it.
I've had customers ask me to remove the engine to do it and I've had them say cut it and save me $$$!!
Pulling the engine/trans/subframe assembly out is a long tedious process on these. NOTHING like a car, twice as complicated as any car I've ever worked on (though I haven't dealt too much with later model transverse-mounted FWD stuff).
