We have a Switch 2 on route for such testing. There are documented instances of regular SD cards working in SD Express card ports but we must remember these are two separate interfaces, the SD Express using PCIe 3.0 x1 (single lane) while SD cards are UHS-1/2. One must consider that if they are using a regular SD card in an SDExpress slot, it would be much like racing a Corvette through mud. Game load times and all other input/output functions would slow to a crawl making this combination of SD card in a SDExpress slot totally unfeasiible.
