Is it possible to convert existing native files to furnace?

[Sunscraper]

For example, if you wanted to import a Plok! song to the tracker (SPC), could you implement a feature that allows you to import and modify existing SPC files?

I'd imagine tildarrow will say no, as spc is like a vgm but for snes, and they already rejected vgm import
