I'm not looking 6-9 months down the road, which you obviously are. That's 6+ months of crappy, exploitive gameplay.
As far as your last quote, having the enemy jump in and out of a Neutral's borders to possibly take advantage of shielding isn't good gaming at all. Telling someone it would be their fault for trying to PvP inside of the area isn't necessarily a good fix. It would just lead to people jumping in and out of the area with some Neutrals running around trying to be dolts.

Been playing DF since the first day of release. GPS will teach you how to blue shield.
Go back and read... The Neutral tribe area is exactly what I'm talking about. You assume the Neutral would attack both people with regard to the OP's suggestion. Anyone jumping into their area would be doing so for an obvious reason (friendly with them).
I'll buy 3-4 accounts and throw up Neutral tribes around your claim, and we can all be happy. Right?
