It is amazing what changing a note can do. Clawhamer is a real option for you to learn but no matter what >> for all those great dorian tunes and songs I would say try adding a C note   on the second string instead of the B , . This tuning (gDGCD)is called Saw-Mill Tuning in older circles. To hear it listen to Tim Hart's clawhammer banjo in Skew Ball or Black Leg minner or Mad Tom of Bedlem all from early Steen Eye Span . THat G sus 4 Tuning is very good for old English dance tunes on Guitar as well. I just worked up " Mr Beverage's Maggot " using ( DGDGCD ) on guitar   . Have fun with it . Later you can do the same with D tuning . Its how I found everyones old faverite ( DADGAD ) .
