Need help deciding on stats

I'm working on a Mork Borg hack based off of Demon Slayer. It's nothing I think I'll end up sending anywhere, it's more or less just something I might use with my friends once or twice.

My current mock up uses Three-ish Stats atm

Resolve - Strength, displaying raw emotion, and withstanding Effects.

Coordination - Speed, applying precision, and dodging Melee Attacks.

Awareness - Perception, deducing facts, and dodging Ranged Attacks

The reason I say "Three-ish" is because I'm exploring the idea of having a Fourth Stat the players get to develop/customize that has an additional mechanical benefit when used (maybe it recovers an Omen or something when it's applicable idk).
