Hi guys, after doing some searching and getting lost even after refining the search choices a million times, i gotsta ask for some help

. I play in a metal band (
http://www.myspace.com/functioncease) in standard C tuning (C-G-C-F) on a laky 55-01. Up till now I've been tuning my DR highbeam medium gauge's down, E to C, A to G etc. and leaving the B for dissonant open semitone stuff

Anyway, just recently I was thinking of getting a light gauge set of 5 string lowriders and tuning everything up from B (B-C, E-G, A-C, D-F) would this work? Or will the tension be too strong for my poor maple neck even with the light gauge? Cheers if anyone answers, you can delete this if its a painfully overasked question Mr Moderator.
Cheers Rayle XoX
