Well it is a little difficult to tell, because I am unsure of your drawings as to whether you have drawn just the metal or the seal as well, plus it is the shape of the bearing surface that will really define whether it works.
In my experience, once the cones start to go then the inner race will as well. Sometimes the cones get some water damage from being left to stand in damp conditions, and a change of cones and balls are all that are required, but your cones are trashed.
In your situation I would be looking to replace the hub/axle/cones as one unit, then find someone to weave the rim onto it. Is the hub a standard size?
