Ohh that's a very interesting idea. Wonder if you could actually make something sound significantly better like that. But like you say, people might have rather different ideas on what sounds better.

And after a lifetime of equal temperament, that's what sounds good to me, anything else sounds out of tune. (I haven't experimented to see if even proper perfect 4ths and 5ths sound out of tune to me! That would be weird. Though those notes are very close to their equal temperament versions I think.) I used to have some music software that came with hundreds of different historical temperaments and tunings, from many different traditions, it was fascinating playing around with.
