I find the photo to be inconclusive. Another, from the side and/or back of the slug might reveal a lot more, because what I'm looking at could also be from a deformed type bar. The point is to inspect the condition of the solder. It doesn't happen often, but I have had machines with cracked solder joints, which of course meant the slug was out of alignment.

Hmm...
That makes me want to try removing a slug completely, cleaning off all the solder, and re-attaching it with ordinary 63/37 electronics solder to see if that works.

Or has this been tried before?

The only way that I'm aware of to correctly solder type slugs onto the type bars is with a soldering jig. This jig holds the slug in the typing position, the type bar is then lowered into the slug and the two are soldered together. Hope this helps,

Makes me believe resoldering a slug is even harder than soldering it correctly in the first place. Starting with a clean slug you can fix it where you want it, position the typebar and apply solder. For an existing slug you would have to either clean the old solder from the joint first, secure the slug in the jig hot with the existing solder melted, or have an even more special spring loaded jig that would allow you to grasp a slightly misaligned slug, flow the solder, and have it pop into the correct position. If I were absolutely determined to do this I think I would go with option (1) improvise a jig to hold it statically in right position then first desolder and clean the thing.

With the right tools it would not require genius to do it right.
