Well, if they're beaters, practice honing and evening out the bevels. Any time that you're establishing a new apex you can influence where that new apex will occur to a degree. So you can gradually move the apex toward having even bevels. If you even out the bevel reveals you are essentially following the grind so if the razor has a wonky grind there is only so much that you can do without a regrind. Minor regrind operations can be done by hand with sand paper and a cork or some other form.
Like I said, 'A lot can be learned from these problem razors'.
