That might make your vehicle not Street Legal soon since backup cameras are required equipment going forward. Not sure how after-market factors in though.
EDIT: I think I was incorrect. The law says "an altered vehicle that was completed on or after this date that was equipped with a rearview camera that already meets the new rearview requirements must continue to meet these requirements after the alterations."

But I'm not sure how broadly that actually applies. So I don't know.
It sounds like installers won't be able to do this modification moving forward either, so you would have to do it DIY.
