D&D 5E Races with floating bonuses: Designing from scratch

[TerraDave]

Eliminate racial ASIs and increase point buy by 5 points. Standard array becomes 16, 14, 13, 12, 11, 10, if you roll stats you roll 4d6 drop lowest 7 times and drop the lowest of those. Merge racial proficiencies into backgrounds. Races that still stand out as significantly more powerful than the baseline can have some of their features turned into Feats.

Pretty much this.

Races give a few smallish things, dark vision and talking to badgers, say, humans might get an extra skill.

Have a list of starting feats--this leaves off the more interesting ones, for latter--and can include things like Orc Berserker. DM can decide if you can take cross racial feats or not.

Finally, for campaigns that don't use feats, then the +2 to one ability score of choice is taken instead.
