You are obviously trying to live in the US because of your wife's OPT status.

Your other plans could have been handled with a better timed entry.

A quick return is not likely to be viewed favorably since you could wait and enter on H4.

By the way, how could you afford not to work for such a long period of time? Someone in their 30s normally has to work; you could be viewed as having worked illegally even if you have not done so.

I suggest you discuss your plans with an attorney because no one on the forum should suggest acts that might be assumed to be contrary to US law.
