Nut With Different Radius Than Neck

[IPA or death]

I found out that the Floyd Rose locking nut has a 10" radius. I planned on having a 14" radius on my fretboard. Is this a bad idea or would it not make much of a difference? Would a compromise of a 12" radius fretboard be good enough? Please, any advice would be greatly appreciated.

10" to 14" conical radius would probably fix that problem right up. But I never trust the printed specs of a locking nut radius. I'll rig it up with strings and use 'under the strings' radius gauges to see what radius it really is (often on a locking nut, it's never a perfect radius), but comforable nut action is an absolute must for me on a guitar, so I think the compromises should be kept to an absolute minimum. Mole hills suddenly become mountains when it comes to tweaking a guitar nut.
