I think this was mentioned above. However I bought my son a baritone uke. I think I found a baritone uke chord book at amazon.com . The bottom 4 strings of a guitar are not going to give you the effect of the full six. But if you learn the chords that you feel are missing the most of what youre looking for in higher positions you may be able to aquire the chords that work for you, and teach yourself a lil more about travling up the neck on the 6string at the same time.
For open tunings I normally use GDGB or DGBD on my four strings
I understand your position and after building a 4 string I can tell you I was not impressed with the DGBE tuning at all. I think for me the open G tuning is the best GDGB. I have just been in to the building lately so now trying to play the thing I guess just look up banjo chords and you should be fine. I may try that to see how it sounds. I am trying to do the same thing with county type church songs.
