With the SYE and new driveshaft, yes, you can remove the t-case drop, but once you do this, you'll want to recheck your pinion/driveshaft angles to make sure they're still good (shim axle as necessary).
I used the case drop after the hack and tap for about a year, and switched over to Rusty's Crossmember with the 1" drop. Doesn't drop as much as stock with the drop but worked great and made the area flatter. Check it out. I also went with his trans mount which is a good time to replace it.
