I could upload .cons to my personal webspace I guess, but as I mentioned they don’t have the easy/medium difficulties charted yet. So I don’t know if there’s much use for uploading anything right now?

Reduction is the least of the issues, if any. But it would help going through those songs in Reaper to check them out and see what kind of work is needed, how MIDI files we have for vocals fit with the tempo map (for thos eof us working with MIDI files), etc. Or, if you work in Reaper, just the original Reaper projects with the audio files.
