Is it possible to fix Takahashi?

First I checked the wiki, however the page on Takahashi provides no indication to whether or not he can be fixed, just that Mayor McDonough will not allow it. Takahashi's wikia page.

One discussion I found on steam postulates that maybe hacking into, and then moving Takahashi to another location outside of Diamond city could fix him. However it seems all this accomplishes is that Takahashi will no longer sell you noodles, from this discussion.

So, according to experiments and gameplay so far, no he cannot be fixed.
