Conjecture about Guild vs. Guild

What if by GvG they mean it's a GW-like setting where you face a random guild (or one similar in rank) and you take out each opposing member's Arena teams. Once you beat a team then your remaining characters are able to move on with the same cool downs, health, and Protection as when you finished your first battle then you have to work together and take down other teams that your guildmates couldn't beat. So everyone in your guild can only use their Arena teams and by the end of the 24-hour limit, or whatever the limit may be, you get rewards based on if your guild beat more or less of the opposing Guild's teammates?
