Just for fun; Transposing ANY Score between Major and Minor Key

My friend, @MK_Piano and I were fooling around with some of our scores on a discord call last evening. 

He had the bright idea to modulate something that's written with an intense emphasis on negative emotion, in a minor key, to a major key. (I have no idea why I've never thought of this lol)

This can be done by selecting all notes in the score, and transposing up by a third, diatonically. (Obviously this doesn't take into account any off-key chords used throughout the score, but the result is just as fun to playback lol). Adversely, you can do this in reverse to a score written in a major key. 

Here's an example, where I've instead of modulating between relative major/minor, I've went through the trouble of modulating to the Major of the same key. (C minor to C major). I used my Halloween Submission as a test dummy because why not. Hah!!! Take a listen:
