Hi Al,

Here is a useful String gauge tension calculator

which I use a lot in calculating suitable string guages for unusual instruments and various tuning to get an even and appropriate tension across all strings.

I hope this might help in calculating suitable gauges. If you dial in your normal setup, you can see what your guitar is accustomed to and then try suitable gauges for the new tuning.

An alternative would be to keep your current string gauges and tune DOWN and then capo, e.g. at the second fret to reach the higher notes.

Hope this helps...

Peace
