Faction Update Question - "Capturing" Zones

As I am currently creating a world in preparation for the far away update of Factions, I do have a question about them. Would it be possible to have a system of warfare like “capturing” regions. I feel like it could be similar to something like Foxhole except instead of destroying the base, maybe a majority of one faction in proximity to a landmark or just in the zone means it is theirs? This would create some interesting warfare in the game similar to PvP MMOs like the previously mentioned Foxhole.

If this is not possible, I do understand, as long as zone allegiance can be changed manually without deactivating and reactivating the region.
