Saving enough to have year without much income?

Are small business owners capable of planning for a year where they keep their money inside of their business for the year to have a lower EFC? How in depth would the CSS Profile go in on this? My dad and mom own a company together with <50 employees, so they would not be required to report the value on the FAFSA. I know savings get counted at a lesser percent compared to Annual Gross Income. If you dropped all income besides maybe 30k family income with moderate savings, would you get substantial financial aid from 100% needs-met schools? I realize it is unethical. I'm already a senior, so this opportunity would have passed for my family already.
