Athlon XP3000+ overclock advice?

I have an Abit NF7-S2 (socket A) motherboard, whose BIOS supports
FSB tweaking in 1MHz increments, but doesn't provide a way to
change the CPU multiplier.

I would quite like to take a second-hand AXDA3000DKV4D chip and
tweak it to run at 13.5x166 = 2250MHz (it's been my experience that
Barton CPUs are noticeably less stable at 2300MHz than at 2250MHz).

Once I've comprehensively tested its stability at 13.0x173 MHz,
I plan to take a very sharp scalpel and cut bridge 0 of L3
(as suggested by http://fab51.com/cpu/barton/athlon-e23.html )

Assuming I don't make a mess of this procedure, can I expect that:

* if the CPU is unlocked or locked, the multiplier will be changed?

* if the CPU is super-locked, the multiplier will remain unchanged,
but the CPU won't display any signs of damage in operation?
