Techmoan has a video where he explains and shows that reading 78s with a microgroove head gives very bad results, low sound, high noise, and no bass. It's a workaround, not a workable solution; you need a special 78RPM head which exist but are rare and expensive. Basically the technical reason is that the 33/45 record groove is read laterally, while the 78 groove is read vertically. So both cannot be properly achieved with the same reading apparatus.
