I think too much material would need to be milled off to make it solid again, so I think it will have to be filled with something.
You'll have to clean it to see how deep. Maybe you can tell it's not as lite as I see it but you cann't really tell how bad. I've cleaned stuff like this, heads, with Oven Cleaner. Others have used a soak in Simple Green. Either one will discolor the metal if allowed to dry. Just look at my cylinder heads and see.
The proper fix I suppose is to have it welded up, filled with Aluminum, and then milled. I don't know anything about something like that except I take it to someone else. I do know about epoxy and such things I have done but in this instance and this machine I don't think the shadetree quicky is called for.
