There are rumor's that DJI is working on make the mini compatible with the SC with a very short range of transmission but for the moment the answer is no. Not possible.
I fly Mavic 2 Pro and wanted the Mini and fly M2P with Smart Controller and asked the same question in the DJI store in Copenhagen - answer was no. I think DJI make a big mistake not allowing the SC to bee used with the Mini. I will buy it if possible to fly it with MC
