I don't think so. One Tamriel will "battle level" in your character's opposing two alliance areas. Presumably, you'll do the bulk of your leveling in your own alliance. The zoning levels for your own alliance will remain unchanged. For example:
You start a character in the Aldmeri Dominion. Each zone in the AD will be leveled as listed above. However, if you took your level 5 character to the Daggerfall Covenant, the game will battle level you to CP140. For you, the enemies you encounter in the DC will be CP160. You'll still have a tough time at your level. Why? (1) the enemies are still above your level, and (2) your skill lines haven't been leveled up yet, so you'll be operating with low-leveled skills.
