Here is another suggestion.
Tune the guitar down a whole tone but in standard, put a partial capo, on the second fret covering strings 543, you re now in dadgad, you can also play in g in this position using, a g6 shape for g, a c shape is the same and the d shape is the samebut leave the first string open, playing ing like this enables you toplay lots of interesting bass runs.
the partial capo as if you were playing in dadgad for d major is not so good for playing tunes but good for the dadgad chordal sound, then when you playin g it is more of a standard sound.
you can also play in g with a different approach partial capo covering   strings 432, this gives the sound of open g tuning.hope this helps.
