Dream on, 410. Most pilots have a resistance to change that would put the Vatican to shame. Even if it was to be made compulsory, there'd be some who'd simply refuse to do it or offset one mile left just to be different.(!)
I've had a conversation on this subject with a mate in Australian CASA and he assures me the mathmeticians have proven to him that offsetting INCREASES the chances of collision. Something about having to re-draw the existing airways' dimensions to allow for it.
Can't see it myself, but there you go...
