At first sight, the /e/ OS ROM e-.0.7-nougat can work with the bootloader and baseband of the StockROM Android Oreo 8.0.0.
With Samsung devices with StockROM Oero 8.0.0 and /e/ OS Nougart 7.0 ROMs I have not made this experience. There bootloop, not recognizing the SIM card, missing IMEI and baseband information were found and therefore the devices were not usable.
First suggestions for improvement, like adding the feature FMRadio and updating Webview 78.0.3904.108 to 79.0.3945.116 are available on gitlab.
