I don't see how it would be an issue if you invested in a ultra high performance tire like a star spec, rs3, or RE-11 that are designed for autox and light track days. These have super stiff sidewalls for top handling under heavy point loads. These may not be as stiff as a RFT but they are certainly more stiff than most performance tires.
Personally I'm investing in Dunlop Star Specs once my RFTs are out. I've had track and autox experience with these and they perform like crazy and have great tread life.
With that being said; I do agree that running regular summer tires would be unsafe because they will roll over before the rears in a turn causing a violent oversteer
