I did this recently. Once I removed the crossmember, I was able to remove the oil pan. It's a tight fit, but can be done. Basically, drop the crossmember, and then remove all the bolts from the oil pan. Pull the front of the oil pan down, and remove the two bolts that hold the oil pump onto the engine block. You can get in there with a 9/16" wrench. Lower the oil pump into the pan, and then slide the oil pan forward until you clear the center drag link.
Another way would be to remove the crossmember and also the center drag link. Then you can lower the oil pan straight down without removing the oil pump.
Of course, I am assuming you're talking about a stock oil pan...
