It was a couple of years ago, but IIRC Wind Armor is just a more flavored version of Mage Armor. It should give +4 deflection to AC, which is very slightly better than Mage Armor which gives an armor bonus (tho deflection doesn't stack with rings), but it had some extras against ranged attacks, maybe the reason why having it 2nd level. Also IIRC the duration was very long, probably the same 1 hour/lv.
Is it impossible for you to just use Mage Armor? Does it really have to be 2nd level?
About Breeze I seem to remember that it basically did nothing

it was just a very flavorful little cantrip that you could use to create effects for no particular benefits, at least no benefit in combat for sure. Its use reminded me of Prestidigitation although that popular cantrip of course has completely different effects... You could add a new use of Prestidigitation consisting in creating a weak gust of wind, but I am afraid this is not what you want.
