Depends on the guitar scale length and the string gauge. If the guitar has a 25.5 scale and you're decked out with 12s go right ahead. If the guitar you're talking about has a 24.75 scale and it's fitted with 09s you're not going to be able to tune anywhere near that, it won't stay in tune half a minute if you can even do it.

You would tune to a B by either using a 7 string guitar or tuning the lowest string 5 semitones and all the other strings down three.

Start:
e
b
g
D
A
E

tuned to b:
Db
Ab
e
b
F#
B
