Yes j.Taylor, just about anything is possible. What you would need to do is design & 3D print a plate as a shim that would attach where those 2 thumb screws are and then find a way to then attach the ZWO bracket.
Sorry to say I don't think their is a shim or an easy way to mount right now, but I would expect someone to have that GSO focuser which is very popular and then design a shim/plate that then would attach the ZWO EAF bracket to the bottom of the focuser.
I know there are 1 other motor focuser company that has made an adapter to mount and use their motor but that bracket would take some thinking and work to use. Depending on how creative you are you could order an EAF and then when you have to find a way to mount it, that would be secure.
Web search for a very popular 3D design web site that has a few 3D mounts and you can download the .stl file and have it 3D printed.
So yes it can be done, but maybe later this year someone will have a way, it's the EAF are on back order here in the US, so when they become in the hands of users I expect to see an adapter.
