Super!

Have you considered 10-12-14-17 (or, in some cases, 9-11-13-15) for the
diminished 7th?

The augmented triad can be more tricky. Here's a list of possibilities,
all of them smoother than 3tET to my ear...

1)The "literal" translation, 1/1-5/4-25/16, pretty tense
2)"Classical" version, 1/1-5/4-8/5, very similar to #1
3)1/1-5/4-19/12, still spacy enough for most applications
4)8-10-13, too smooth for many applications

True, but do the 3rds matter as much as the 5ths?
