You can replace SteamVR with OpenXR by using Opencomposite and yes it does work. I use it for IL2 and it works perfectly. It worked for DCS before DCS came out with native OpenXR. It's not needed now. Same for MSFS which is native OpenXR. Opencomposite doesn't work for every game, there's a long list of those that don't work, and unfortunately AH is one of them. I spent an afternoon online with the dev of Opencomposite trying to get it to work with AH. If he couldn't get it to work I don't see how you did. AH is SteamVR only. I've asked HT about making it compatible with OpenXR but he wasn't interested. Can't imagine that'd be a major deal as OpenXR is the basis for all things VR. But that is what that is.
