Then you and your mom would be committing fraud. The federal government is not the people who you want to defraud.
You and your mom could face jail time, you and your mom will be responsible for repaying all aid that you received as a result of your completing fraudulent forms, you will be kicked out of school or have your degree rescinded.
The information will show up if you ever apply for a job where a back ground check or security clearance is necessary. Since everything goes through the IRS (and you will have to submit 2016 tax information this for 2018-2019 and 2017 information for 2019-2020), it would be found out soon enough. The schools that provide the most financial aid will most likely still ask for the income and assets of both of your parents.
Instead of looking for ways to defraud the government, find our how much they are willing to pay for school and make sure that you compose a list where you have some financially feasible options.
ETA: since you are applying to CUNY, are your working? You can help your parents split the costs.
