Is it possible for part of an IL2CPP project to use mono backend?

Unity 2018.4 Hi. I'm building my project using IL2CPP, but a package I'm using (AudioImporter, which uses the NAudio lib for mp3 file loading) throws errors in the IL2CPP build. Is it possible to somehow uses this package built with the mono backend within my IL2CPP main project? Seems unlikely but thought I'd ask. Or would I have to run it as a separate service and use some form of IPC? Thanks
