Actually, your plan has excellent odds of succeeding, as long as you know that you will be required to pay OOS for your first year. You will have to appeal after your Frosh year, and after your 'rents have relocated, but the appeal will likely be granted. In other words, you will definitely pay OOS fees during your Frosh year, but you would appeal during the summer before your second year.
At worst, your appeal is denied for Soph year, but if your family is still instate by your Junior year, it would be extremely hard for UC to turn it down.
