Sounds like not much fun. We have many friends and customers on LHT's with a variety of handlebar styles, albatross, moustache & drops. Prior to spending any more money take a few minutes and read the Bike Hermits blog about touring bike fit - some of it will be redundant for you but perhaps you will glean some minor adjusting you can do to help for the time being.
Good luck!
I have been fighting comfort on my Gilles Berthoud Saddle and after measuring my sit bones (duh) realized the issue was the saddle width and shape (pear), went back to my fizik vitesse (t shape) and while the nose is a bit long the sit bones are very happy. With the change I also lowered my Nitto Grand Randonneur handlebars about a centimeter so totally get the tweaking.
