Arrow Encrypted Game Manual - Could we crack it?

FIRST FRC Password Convention:

Past three years:
2014: 3Zones2Goals1Alliance!
2013: sAucersFlyRobotsClimb!
2012: !HotShots!KnowBalance!
2011: 5Time4For3Robots2To1Dance!

Uses AESv2 128 bit for PDF encryption

At first glance, it seems pretty secure. However there seem to be a lot of patterns as to how the passwords are chosen.

Patterns:
1) always 22 characters after 2011
2) all of the words used are english and would appear in the dictionary
3) they use mixed case
4) a word is never separated by anything special, and no character substitution is used
5) only around 3 or 4 words are used
6) they always end with a "!" character
7) in all years but 2013 the first character has not been a letter

Idea:
Create a program that generates a wordlist based on the rules FIRST seems to follow when creating the passwords, split the wordlist up into smaller segments, and let different teams try different segments until the correct key is recovered


Thoughts?
