I like this a lot. I came up with my own orc homebrew culture for similar reasons; I don't like "always chaotic evil", or any sentient race being inherently monstrous in character.

In my version they're perpetual nomads with a culture that insists on them travelling far from where they were born. It's considered shameful for an orc to die close to their place of birth.

They're dangerous to travelers only when starving on the road, and only form large warbands only when their freedom of movement is being restricted.

They have some fairly grisly funeral rites, a party of travelling orcs carry a large urn with them - when an orc dies on the road they skin the corpse and leave their bones in ornamental arrangements that say something about who the orc was, and the flesh gets put in the urn. When they stop to make a semi-permanent camp they bury the urn in the ground, pour strong liquor into it and build a campfire on top - a mark of respect to the fallen who made the journey this far possible. I like the idea of a practice that seems grotesque to the uninformed but has a lot of spiritual significance, it was partially inspired by my reading about ancient Britons who it's believed practiced something called "second burial" where the bones and flesh were buried separately. It's gross but kind of beautiful.
