Pack Creation/Group Creation

Pack Application states that if im thinking about creating a pack to post it in the Pack Formation Page with all the required info. By my understanding, you will get the green or red light. What if I want to begin getting members of the pack by forming an unofficial group first? Would this be an acceptable way to gain members and reach the 50+ post limit? The character I plan on doing it with does not meet the 50+ posts or 1 month longevity.
