If I was to consider my own list, it'd be more broad with the categories of:
1. Closer to 5e Mechanics/Toned Back Homebrew 2. Non-Origin Companions (Not Mercenary System) 3. Fix Conjuration and Summoning
Too broad. Sets you up for disappointment.
Remind me never to let you cast any wish spells. Haha.
To be fair, under each of those is long lists of individual changes and wants that go to the minutiae, just I have ranted much on most of them. Also don't give me a Wish spell because I will spend hours just thinking up the phrasing to get EXACTLY what I want with it (or will be broad because I know the DM also likes to have fun and sometimes sowing Chaos is the best way for fun~)
