Using the unit weight of any string (as provided in the tension guides already suggested), one may calculate the tension of any string, at any pitch, on any scale length: String Tension
At last, another human being that is contemplating this tuning! (Certainly there must be more of us out there...)
I'm also considering the following in a 4- or 5-string configuration (36" scale): C1 G1 D2 A2 (E3) or D1 A1 E2 B2 (F#3)
Perhaps just 4-strings would suffice (at a 32" scale): E1...
