If you try that the strings will likely break and hurt like a bitch when they do. It would also warp the neck like a mother****er. If you want the lowness of a baritone, but still want standard, maybe you should check out a 7 string guitar.
#4
higher guage strings or popped strings. and maybe destroyed neck.

at least 11s or 12s.
