Only on a 50- 50 chance up to M/M difficulty. On Hard and VH it will not work; the AI is insanely player-hating. Such is EB. If a faction has a land border with you it will usually attack, and I can assure you that AS will.

A better plan is to invade all provinces in the border region, sack them, leave them and let them rebel (or give them to another faction). When you no longer has a land border with them, they will stop attacking you and likely sue for peace.
