Transfer Pokemon from ROMHack to Nintendo Switch

First of all, I'm sorry if this post could not be 100% related to this group but I can't find anything on the web. I usually play ROMHack (in this period Drayano's Storm Silver) and I'd like to know if it's possible to transfer Pokemon from ROMs/ROMhacks to Nintendo Switch games. I play them through emulator but I've got a Nintendo Ds Lite with R4 too so it's easy to access .sav files. Does anyone have any tips? Maybe using some sort of sysbot? I hope to catch your interest as I think it could be fun to have your Pokémon in real games too after having spent time to get and train them.
