Nice, did not find one yet. That means all you have to do is hire some guy who is good enought for you as an avatar and go change him up.
With the avatar the problem imo is that when he dies the game should be over right, but at the same time it shouldn’t cuz you are the commander. This kind of confusion would not go well. But I’m still remembering suggestions from early stage of EA about this. It all ended up with either no personalization or being able to very limited customization for your first three dudes. Something like one of the rimworld mods do where you have a pool of points that you can buy items perks backgrounds from. With the current state of the game still do not see an avatar thing being good, but the starting dudes customization might be quite amusing.
