I've got the same problem as well. I'm considering turning the DB8 towards Hickory in order to pickup WHKY and I noticed that when I did this with my smaller homemade antenna I could pickup WUNE. That would eliminate the need for WUNG. The only issue I'd have with that would be the stations in E. CLT, namely WCCB, WSOC, WTVI, and WAXN. I'm not worried too much about 18 or 9, as they are nice strong stations here. WTVI will be an issue because the DB8 isn't a very good VHF antenna. WAXN I can live without. (I wish WSOC would do more with it.)
Since WTVI is VHF, it can be fixed with a simple dipole and it would be easy to add in. I'd like to get WNSC in Rock Hill but that really doesn't seem possible with this setup.
Since I don't know your location this might not work for you but here is some info on the DB8. The DB8 has a pretty nice lobe at +/- 45 degrees so you might be able to use this to your advantage. i.e. you will get good pickup in these directions. There is also a smaller lobe in the back. There is a major null at +/- 30 degrees and a lesser one at 90 degrees. You won't be able to pickup much in these directions. You could add a second antenna pointed in these NULL directions relative to the antenna, to avoid phase issues. (above assumes 0 degrees is front of antenna)
Without the right equipment combining, antennas is a bit of a trial and error exercise. If you don't mind doing a little "engineering", I would combine the antennas with old school twin lead wire, and then put a single balum off that to connect to coax. This way you avoid the 3db loss of using a coax splitter. Well.... theoretically. I haven't tried it in practice.
