You can invent whatever system you want, like the one you proposed here, but if the outcome is disproportionate then it is, by definition, a racist system.
Why? Because race is a construct. It’s fake. Factually speaking, the only differences between these constructed racial groups are things like hair texture and skin pigmentation. Anyone saying otherwise is lying to preserve the construct.
If your values include a rejection of racism, you need to create a system that achieves the outcome of proportionate access to opportunity and proportionate control of wealth. Affirmative Action is the system that got the USA closest to achieving that outcome.
