So Tasha's is bringing an updated custom lineage race, with the following racial features:
- +2 to any stat of your choice
- Darkvision or one skill proficiency
- A feat
You can pick any race and replace your racial features with the above. So you could just list this option as it's own race and add "Appearance: pick a playable race, you look like that"
As you're getting +2 and a feat, you can get a total of +3 to any one ability score. Meaning you can point buy up to 15 and start with an 18. Here's a list of those feats courtesy of
GitP. It's worth mentioning that a lot of the racial only feats may lose their racial restrictions, meaning elven accuracy and squat nimbleness might become widely available.
It's also worth noting that a halfling and dwarf's "speed" is a racial feature, and on the custom lineage they might not have the arbitrary 5ft movement penalty... so a lineage halfling barbarian with the squat nimbleness feat could be moving at 35 ft per round at level 1, with 18 strength.

When it's out I'm probably going to rewrite the master class / race post into something a bit easier to digest.
