That was already done. The (in)famous Bleakers roleplay.
From that time ZoS has officially stated that keep flipping is against the rules. The worst offenders were banned and AP was stripped from them.
In July the midsummer mayhem event starts. If I recall correctly, the boxes had akaviri motifs. That will be the easiest way to get them. Or paying gold to a pvper with tons of ap.
Ways to get good AP quickly
1. Play Battlegrounds, you get decent AP whether you win or lose,
2. Follow a zerg in Cyrodiil, light attack all the enemies, heal all the allies you can.
3. Wait for Midyear Mayhem (probably in July) for double AP and a chance at akaviri motifs in the reward boxes, and use either 1 or 2.
Mind you, getting the amount of AP you need is still going to take a lot of time. Personally, you might consider whether its easier to earn the AP or the gold. I PVP and farm regularly and still can get the gold quicker than the AP.
