Steering ratio doubler advice.

I have a '71 Dart Swinger and am in the process of replacing my front suspension with QA1 and PST parts. The car originally had power steering and I'm swapping it out for a 24:1 manual steering box.
The plan was to convert to electric power steering and get a 16:1 manual steering box from PST.
My question is, can you run a 2:1 doubler on a street driven car? That would effectively make my 24:1 box a 12:1. I know doublers tend to be race car only parts, and don't want to create an unsafe or dangerous car to drive on the street. I would like to autocross occasionally, but this will be a daily driver when the weather is nice.
