Besides OpenSPC, are there any SPC to MOD converters?
Besides the old SNEmul, nope. (but then again, the mod ripper completely sucked.

)
Edit:
I finally managed to build OpenSPC. (hint: delete the included "allegro.h" file from the source code)
I modfied the program to support fractional update rates, so it can generate better IT files.
This is completely epic. Is it still command line, or did you give it a pretty GUI?
I loved OpenSPC completely for this reason. Too bad the SNeSe core is fail. You could use blargg's APU core if you wanted to.
