Alternate ASI/feat progression

So for reference, my prior experience is 3e and pathfinder 1e, which we always joking called 3.75e. While I like a lot of the changes in 5e, the ASI/feat system just feels icky to me. For reference, in 3e, everyone gets 1 feat at level 1, then a feat every 3 character levels. Some classes, like fighters, get bonus feats, and humans get an additional feat at level 1. That said, the power level of 3e feats is closer to a half feat in 5e. For example, Combat Casting in 3e is roughly on par with advantage to concentration checks part of War Caster. This is mainly focused on 2014 rules.

So, the fundamental issue I have is that the feat system as written makes characters feel very generic. If I say I am playing a level 8 High Elf Wizard, odds are most veteran players could guess my stats, and recreate my character sheet with about a 95% accuracy.

So, I want a set of rules that makes certain feats not feel mandatory. I want to encourage players to take interesting options without creating a balancing nightmare. Here are my thoughts.

1. Variant human and custom lineage are not available. Players can use the stat swaps from Tasha's race customization. Humans gain a skill profiency of their choice.

2. ASI from class levels can not be traded for feats. In addition, characters cannot have a stat higher than 17 at level 1, or a stat higher than 19 at level 4.

3. Everyone gets a feat at character levels 1, 4, 8, 12, 16, and 20.

4. Homebrew some new feats. For example, a feat that gives advantage to concentration checks and a +1 to a stat.

So my questions are. Are there any balance issues I am missing? Will this actual encourage more character diversity or will I end up with everyone playing High Elf Wizards with the obviously best feats? Are there any other homebrew or third party systems out there that trying to handle ASI and feats differently?
