The tension on the G (A) is a little firmer than I like, but since this is such an "abnormal" (dare I say "obscure"?) tuning, I don't see any string makers rushing out to accommodate any time soon...
Check out kalium strings!
The have a string tension calculator where you can enter your scale length and then pick a string Guage based on the tension at a given note.
For a balanced NST set with each string around 40 pounds your set would look something like
C - 0.130
G - 0.086
D - 0.057
A - 0.037
