MagicCombo - managing long lists

I was going to try building a keymap that would use a long list of combos: 26 in fact as each letter would be a chord, with one, two or three keys as defined on the RxCy matrix. I think this means using MagicCombo. Is there a short, readable way to populate a list of combos than that given in the MagicCombo example, or even the keymap in this thread?

Would it be possible to do it using the newer “Chord” plugin? Ironically I don’t want to have any keycodes assigned to the keys that form chords, so could I use the RxCy codes instead?
